Hello, I am writing a bootloader for the P89LPC922. I use IAP lite to write to the program memory and this works fine. I want to reprogram UCFG1 (RPE) before updating the firmware to prevent unwanted reset requests during updating. How can I program UCFG1 with IAP? I tried the IAP sources on www.esacademy.com, but they don't seem to work :(

Hello, I want to use the PWM to dim a LED. This led is connected with a 470 Ohm resistor to 5VDC. The controller is running on 3VDC. I want to set the output of the PWM (T0) in open drain mode (set P1M1 and P1M2 bit). Somehow this doesn't work. The same problem occurs with bi-directional async communication. I have connected RxD and TxD with each

By the way, the data recieved as a general call has never been consistant with the data sent. I have slowed the transfer speed to
