Programming The Internal Flash; Asynchronous Mode - Fujitsu MB91460 SERIES 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 X2 (UART 0)
< Synchronous serial Flash-programming via X1

5.1 Asynchronous Mode

This chapter describes the serial asynchronous programming of the internal flash with the
help of the 'FME-FR Programmer' in automatic mode. For other programming possibilities,
please see the application note mcu-an-300012-e-mb91460_flash_programming.pdf.
1) For serial asynchronous programming SUB-D9 connector X2 which is connected to
UART0 has to be used. The following jumper setting is needed.
