• Bit 5:4 – PSYNC01:0: Synchronization Out for ADC Selection)
Select the polarity and signal source for generating a signal which will be sent to the ADC for
synchronization.
Table 13-10.
• Bit 3 – Reserved.
• Bit 2 – POEN0B: PSCR OUT Part B Output Enable
When this bit is clear, I/O pin affected to PSCOUT01 acts as a standard port.
When this bit is set, I/O pin affected to PSCOUT01 is connected to the PSCR waveform generator B out-
put and is set and clear according to the PSCR operation.
• Bit 1 – Reserved
• Bit 0 – POEN0A: PSCR OUT Part A Output Enable
When this bit is clear, I/O pin affected to PSCOUT00 acts as a standard port.
When this bit is set, I/O pin affected to PSCOUT00 is connected to the PSCR waveform generator A out-
put and is set and clear according to the PSCR operation.
