Debugging programs with MON166 has some side-effects:

  • MON166 can be configured to use the on-chip UART. The target program may use the on-chip UART as long as the UART configuration is not changed. If the serial port, timer, or baud rate configuration are changed, the monitor will lose communication with the µVision Debugger. Characters transmitted by the target appear in the µVision Serial Window. Note that the Stop Program Execution with Serial Interrupt Option must not be checked if your target program uses the serial port.
  • You may use the serial interrupt to signal MON166 to halt program execution. If you enable this option, your target program cannot use the on-chip UART.
