(a) You can use the serial adapter for the entire family of Cygnal processors with JITAG or 2 wire debug interface.
(b) You can preload a bootloader and then use it to program the flash via different pins ( including uart, spi, smbus etc ). First you must use the serial adapter then you can use your own programming firmware.
(c) You can build a JITAG programmer with different controllers and even with the PC only using the parallel interface –
(d) Use a DOS window in win98 or directly run it from Start- Run
