LPC900 ISP and ICP features
« on: February 03, 2006, 10:32:09 pm »
Hi All,

Does ICP have supperior features?

Obviously if you use ISP you need a stable clock source. If you program the flash for external xtals or external clock source.... and you forget  or don't have an external source then you can not program the LPC900.
(becuase you need the baud rate gen for the UART... which is dependant on the osc source)



Where as the ICP is self clocking (mode 0 of the UART)


If you have LPC900 flash programmed for a external xtals or external source....  but have not external xtal or source....  Can you still program the LPC900 with ICP?

Does ICP switch back to internal RC OSC?


I would be intertested to hear your thoughts

Thanks in advance
