Hi, I have a problem when using the LPC932. By Enabling the UART Break Detect Reset through AUXR1 |=0xC0; (also selecting clock low power) the LCP932 does not executed. I know this because in my program I should expect an output on P2 LED's. Then, if I do not choose this UART Break Detect Reset (AUXR = 0x80), the LPC932 works fine. I have tested port2 with the hello and blinky sample programs and it works fine. The com1 port is always connected to the computer. Does anyone know what could be the problem? Here is the configuration and libraries I am using I have a new board and new chip. revision G I need some help thanks.
