23. Advanced User Debugger (AUD)
23.5.4
1. Module standby
2. AUDRST = low-level input
3. Normal operation/software standby
23.5.5
Follow the sequence described below to start up the AUD.
After selecting the AUD pin by the PFC, input at least three clocks to the AUDCK pin while
retaining the AUDRST pin at low level. Then, set the AUD reset bit (AUDSRST) in SYSCR to
clear the AUD reset. Low level input to the AUDRST pin and clock input to the AUDCK pin can
be started prior to the selection of the AUD pin by the PFC.
23.5.6
While using the PD22/AUDCK pin for RAM monitor function, the PE3/AUDATA3,
PE4/AUDATA2, PE5/AUDATA1, PE6/AUDATA0, and PA16/AUDSYNC pins are not
available. Instead of those unavailable pins, the PD19/AUDATA3, PD18/AUDATA2,
PD17/AUDATA1, PD16/AUDATA0 and PD23/AUDSYNC pins must be used.
