Bit 2 – POEN1A: PSC Output 1A Enable
When this bit is clear, I/O pin affected to PSCOUT1A acts as a standard port.
When this bit is set, I/O pin affected to PSCOUT1A is connected to the PSC module 1 waveform generator A out-
put and is set and clear according to the PSC operation.
Bit 1 – POEN0B: PSC Output 0B Enable
When this bit is clear, I/O pin affected to PSCOUT0B acts as a standard port.
When this bit is set, I/O pin affected to PSCOUT0B is connected to the PSC module 0 waveform generator B out-
put and is set and clear according to the PSC operation.
Bit 0 – POEN0A: PSC Output 0A Enable
When this bit is clear, I/O pin affected to PSCOUT0A acts as a standard port.
When this bit is set, I/O pin affected to PSCOUT0A is connected to the PSC module 0 waveform generator A out-
put and is set and clear according to the PSC operation.

PSYNC – PSC Synchro Configuration
Bit 7:6 – Res: Reserved
These bits are reserved and will always read as zero.
Bit 5:4 – PSYNC2[1:0]: Synchronization Out for ADC Selection
Select the polarity and signal source for generating a signal which will be sent from module 2 to the ADC for
synchronization.
Bit 3:2 – PSYNC1[1:0]: Synchronization Out for ADC Selection
Select the polarity and signal source for generating a signal which will be sent from module 1 to the ADC for
synchronization.
Bit 1:0 – PSYNC0[1:0]: Synchronization Out for ADC Selection
Select the polarity and signal source for generating a signal, which will be sent from module 0 to the ADC for
synchronization.
