• Bit 4 – POEN2A: PSC Output 2A Enable
When this bit is clear, I/O pin affected to PSCOUT2A acts as a standard port.
When this bit is set, I/O pin affected to PSCOUT2A is connected to the PSC module 2 waveform generator A output and is
set and clear according to the PSC operation.
• Bit 3 – POEN1B: PSC Output 1B Enable
When this bit is clear, I/O pin affected to PSCOUT1B acts as a standard port.
When this bit is set, I/O pin affected to PSCOUT1B is connected to the PSC module 1 waveform generator B output and is
set and clear according to the PSC operation.
• 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 output 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 output 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 output and is
set and clear according to the PSC operation.
