• Bit 7 – not use
not use
• Bit 6 – not use
not use
• Bit 5 – POEN2B: PSC Output 2B Enable
When this bit is clear, I/O pin affected to PSCOUT2B acts as a standard port.
When this bit is set, I/O pin affected to PSCOUT2B is connected to the PSC module 2 waveform
generator B output and is set and clear according to the PSC operation.
• 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.
