Introduction The Generic FRDC supports Freescale's stand-alone FlexRay communication controllers, MFR4200 MFR4200 and MFR4300/MFR4310 MFR4300/MFR4310, which plugs directly onto the HCS12X HCS12X EVB, and a number of other Freescale EVBs (with adaptor board): FSL MCU MPC500 MPC500 MPC5500 MPC5500 HCS12 HCS12 Adaptor Board FLXRAYADPT500 FLXRAYADPT500 FLXRAYADPT5500 FLXRAYADPT5500 SCFLXRAYADPTS12 SCFLXRAYADPTS12 (not S12X) The required adaptor board must be purchased separately. They are connected together by two IP connectors (logic and I/O). The logic connector routes all interfacing signals and the I/O connector routes a number of other signals for monitoring.

MFR4200 MFR4200 & MFR4300/MFR4310Settings There are slight differences between the pin-outs of MFR4200 MFR4200 and MFR4300/MFR4310 MFR4300/MFR4310 communication controllers. In order to set-up the FRDC for the correct microcontroller, the following features have to be selected: Interface Selection AMI/S12 AMI/S12 Mode through IF_SEL0 / IF_SEL1 pull-down and pull-ups Clockout Selection through CLK_S0 / CLK_S1 pull-down and pull-ups The interface selection for both communication controllers is similar, but the MFR4300/MFR4310 MFR4300/MFR4310 have a CHICLK_CC interface option available, as shown in Tables 1 and 2. Table 1 MFR4200 MFR4200 Interface Selection Table 2 MFR4300 MFR4300 Interface Selection The clockout selection is identical for both communication controllers as shown in Table 3: Table 3 MFR4200 MFR4200 / MFR4300 MFR4300 Clockout Selection The interface selection is chosen through switch 2, as shown in Figure 9. Table 4 shows a comparison of the pin-name differences between the two devices. 5 Figure 9 Interface Selection Switch Table 4 Signal Name Comparison Please note that when using Asynchronous Memory Interface with CHICLK_CC, position 8 of SW2 must be on to connect CHICLK_EN (P1A Pin 48) to CHICLK_CC of MFR4300 MFR4300 (Pin 32). Figure 10 shows the switch settings for CLK_S0 and CLK_S1 for both MFR4200 MFR4200 and MFR4300 MFR4300, since these pins are different on each controller. Figure 10 Clock Output Selection 6 3. FRDC Configuration 3.1 VIO Select Jumper JG1 controls the voltage of VIO_sel which is connected to the Philips physical layer (TJA1080 TJA1080) Vio Pin 4, various pull-up resistors and the MFR4200 MFR4200 and MFR4300 MFR4300 power pins (VDDR, VDDX1, VDDX4, VDDX2 and VDDX3). Either 5V can be selected direct from P1A Pin 24 or 3.3V from the output of U1. Figure 11 VIO Select Position 1-2 = 3.3V Position 2-3 = 5V 3.2 Interrupt Select JG2 selects the interrupt source from the adaptor board's IP Logic Connector [Pin 42(IRQx) and 44(XIRQx)]. The default setting is position 1-2 as the adaptor board routes the IRQ signal through pin 42. Any IRQ jumpers set on the adaptor board will be routed through this setting (IRQx). Figure 12 Interrupt Select 3.3 Reset Select SW1 controls which signal is connected to RESET of the MFR4200 MFR4200 / MFR4300 MFR4300. The following options are possible: Position 1 -External Reset Source (Pin 4 of P1B, IP IO Connector) Position 2 -External Reset Source (Pin 4 of P1B, IP IO Connector) Position 3 -MCU Reset Connected to Pin 3 of the IP Logic Connector (P1A) Position 4 -Manual Reset (push button) Figure 13 Reset Select Switch 7 3.4 Power LEDs There are 3 power LEDs for 3.3V, 5V and 12V. These have varying degrees of brightness and show when the FRDC is correctly powered. Figure 14 Power LEDs 3.5 Physical Layer Settings There are three pull-up and one pull-down resistor options for each physical layer (U2 and U3). The four control options are for the following TJA1080 TJA1080 pins: BGE EN STBN WAKE Bus guardian enable input. Low means transmitter disabled Enable input; high means enabled Standby input; low means low power mode Local wake-up input Table 5 Physical Layer Modes Figure 15 Physical Layer Jumpers Also, the FRDC allows the developer to monitor the Philips TJA1080 TJA1080 Inhibit 1 & 2 outputs. These are output signals for switching the external voltage regulator. The configuration shown below scales the signal down from 12V to 3.3V: 8 INHIBIT1 = (12V * 100 K ) = 3.3V (270 K + 100 K ) JG14 and JG15 are connected to pin 6 and pin 30 of the IP IO Connecter respectively, which in turn are connect to one of the MCU's GPIO pins. Figure 16Inhibit Configuration JG14 Position 1-2 = U2 Inhibit 1 signal, JG15 Position 1-2 = U2 Inhibit 2 signal JG14 Position 2-3 = U3 Inhibit 1 signal, JG15 Position 2-3 = U3 Inhibit 2 signal 3.6 Power Disconnect The power can be disconnected from the MFR4200 MFR4200 / MFR4300 MFR4300 and TJA1080 TJA1080 devices. This is mainly to allow current measurements. JG16 and JG17 disconnect VDDR, VDDXn and VDDA from the MFR4200 MFR4200 / MFR4300 MFR4300. Figure 17MFR4xxx Power Disconnect JG18 JG21 disconnect Vcc, Vbuf and Vbat from Physical Layer Devices U2 & U3. Figure 18 Physical Layer Disconnect Jumpers 9 3.7 Test Points There are various test points around the FRDC. The jumpers can also act as test points when open-ended jumpers are used. 4.
