M66013FP
8-bit Expander with Address
REJ03F0266-0200 Rev.2.00 2008
M66013FP semiconductor that capable performing serial-parallel conversion data. This addresses. microcomputer uses four signal lines CLK, send receive data. adopts types operation modes: echo-back mode normal mode. echo-back mode, data received serial sent sender within same sequence (*1) normal mode, restriction given data sent sender. However, normal mode supports same communication protocol that M66009FP. Note: higher order command bits excluded. Three bits echo-back mode four bits normal mode available addresses. echo-back mode normal mode have types types address, respectively, address set. Receiving serial data from microcomputer, M66013 compares address data included data with address entered address setting. Only when these addresses match each other, specified command provided executed. serial input-parallel output operation, order bits received 16-bit serial data converted parallel data output pins High order bits handled address command bits. Since writing operation data register parallel output outputting operation register contents pins performed with different commands controlled independently, register contents must checked before output specified data pins parallel input-serial output operation, parallel data pins outputted order bits sended 16-bit serial data. contents high order bits sended 16-bit serial data differs using operation mode. echo mode, port output format capable setting either N-ch P-ch open drain. normal mode, port output format fixed P-ch open drain.
Features
capable providing high speed serial communication MHz. Provides modes: echo back mode normal mode. capable reading serial input data echo back mode. (However, bits available address.) capable achieving communication protocol current M66009FP normal mode. (However, bits available address.) Uses different commands operations output data port: command writing data into output register command output operation port. Provides port data read only command. capable reading output register. Adopts decision majority reading three types data when serial data received. capable setting port output format either N-ch P-ch open drain. echo mode) Applications Inter board communication VTR, equipment, expansion microcomputer port, etc.

Basic Protocol Sending Receiving Data
following diagram shows basic protocol sending receiving data between microcomputer M66013. Falling from starts series sequence rising from terminates sequence. concrete operation sequence follows: falling edge 8-bit parallel data pins loaded into shift register serial output. rising edge CLK, input data read into shift register serial input counter counts When address bits read, received address compared with address address start specified operation only when these addresses matches each other. kept high impedance status until address comparison complete. When these addresses match, keeps high impedance status until next sequence. When addresses match each other, operation reading serial data from operation output serial data from synchronization with falling edge carried out. When 16-bit data been completely sent received, following operations carried synchronization with rising edge output placed high impedance status. When counter does count rising edges, operation below skipped counter reset wait next access. When counter value operation writing data register parallel output, operation output port operation setting/resetting data setting flag carried out, counter then reset wait next address.
