The J24 jumper is used to disconnect this optional input. Another external clock can be connected at PCA CLK connector (J23) to control externally the PCA clock (P1.2/ECI). The J25 jumper is used to disconnect this optional input. 2.6 Interface 2.6.1 TWI The TWI connector J9 can be controlled by: - Hardware TWI I/O of MCU (for Product including this feature). The signals TWI_hard_sda and TWI_hard_scl are controlled by the TWI ports of MCU. - Software TWI. This can be done using the J10 and J11 jumpers which respectively connect to TWI_soft_sda and TWI_soft_scl. They can be software driven on standard I/O P3.4 and P3.5 This TWI bus is also connected to the J6 2X24 connector. External TWI pull-ups are not provided on the AT89STK-08 AT89STK-08. 2.6.2 SPI The SPI connector J8 is connected to SPI I/O of the MCU. 2.6.3 RS-232C RS-232C The P1 DB9 connector is connected to on-chip UART peripheral through a RS-232 RS-232 driver/receiver. 2.6.4 Connectors for Card Extension Two 2 x 24 connectors offer an extension to the board. Be careful to plug the MCU board into an extension board correctly: All microcontroller I/Os are available in extension connectors.

First release the RESET button and then the ISP button. The device enters in ISP mode. 3.2 Auto ISP Mode It allows the host PC application (ATMEL Flip software for example) to control the hardware conditions from the serial lines RTS and DTR. Thus with the Auto ISP mode, the user does not need to push the ISP and RESET buttons. 3.2.1 Board Configuration To use Auto ISP mode, put the board in the same configuration as ISP mode and also: Close RTS (J18) jumper Close DTR (J20) jumper AT89STK-08 AT89STK-08 Hardware User Guide 3-9 4368A­80C51 80C51­11/04 ISP Programming 3.3 FLIP Software FLIP software runs on Windows® and Linux® Operating Systems. FLIP supports in-system programming of Flash C51 devices through RS232 RS232. The latest version of FLIP software can be downloaded from the Atmel web site, www.atmel.com. 3.4 Batchisp Software Batchisp is an In-System Programming application which can perform the same operations than FLIP but is designed to be launched from the DOS command window. The main purpose of batchisp is to automate ISP operations on a lot of parts. It may also be launched from an IDE like Keil's uVision2 one : you can compile and link your embedded program, generate the HEX file and download it to the target hardware without leaving the Keil's IDE. This makes embedded software development and test faster. Autoisp function is an operation which allows to enter in ISP mode without any hardware handling.This is done thanks to DTR and RTS RS232 RS232 signals which can control on the Board the RST and PSEN I/O of MCU. 3-10 4368A­80C51 80C51­11/04 AT89STK-08 AT89STK-08 Hardware User Guide Section 4 Appendix A: Board Layout Figure 4-1.
