5 Programming the internal Flash memory
All Flash devices have an internal bootloader for asynchronous- as well as for synchronous-
Flash-programming:
Asynchronous serial Flash programming via X5 or X9 (UART0 or UART2)
Synchronous serial Flash programming via X4 (UART2)
5.1 Asynchronous Mode
This chapter describes the serial asynchronous programming of the internal Flash memory
using „Flash Memory Programmer 16FX‟ in automatic mode.
For serial asynchronous programming SUB-D9 connectors X5 or X9, which are connected to
UART0 and UART2 respectively, can be used on the starter kit.
The following jumper settings are necessary:
