Programming The Internal Flash; Asynchronous Mode - Fujitsu ADA-91270-90340-100PFV V1.0 User Manual

5 Programming the internal Flash

All Flash devices have an internal bootloader for asynchronous- as well as synchronous-
Flash-programming:
< asynchronous-serial Flash-programming via X3 (UART "A") of FLASH-CAN-100P-340
synchronous-serial Flash-programming via X17 ("FlashKit") of FLASH-CAN-100P-340
<

5.1 Asynchronous Mode

The Flash-microcontroller of MB90340, MB96340, and MB91270 Series can be programmed
in circuit by using the freeware "Fujitsu Flash MCU Programmer" that is available on the
Fujitsu Micros CD-ROM or Web Site (http://www.fme.gsdc.de/gsdc.htm: select < Software <
Utilities)
MB90340 and MB96340 Series use UART0 for in circuit programming.
Note: Basically MB96340 supports programming via UART0-URAT3
MB91270 Series uses UART1 for in circuit programming.
Note: Open jumper JP16 of FLASH-CAN-100P-340 because P10 is used for mode selection.
Please check the correct UART selection in chapter 4.4.
The following procedure must be followed to enable Flash Programming:
1. Power off the system
2. Connect the Evaluation Board UART"A" to your serial PC communication port.
A straight cable connection (1:1) has to be used.
3. Check the Jumper-settings according to the UART as described in chapter 4.4.
4. Configure by Dip-Switch S2 the mode related to your microcontroller:

PGM mode
MB96340
