• Bit 3 – POEN2D : PSCOUT23 Output Enable (PSC2 only)
When this bit is clear, second I/O pin affected to PSCOUT23 acts as a standard port.
When this bit is set, second I/O pin affected to PSCOUT23 is connected to the PSC waveform
generator B output and is set and clear according to the PSC operation.
• Bit 2 – POENnB: PSC n OUT Part B Output Enable
When this bit is clear, I/O pin affected to PSCOUTn1 acts as a standard port.
When this bit is set, I/O pin affected to PSCOUTn1 is connected to the PSC waveform generator
B output and is set and clear according to the PSC operation.
• Bit 1 – POEN2C : PSCOUT22 Output Enable (PSC2 only)
When this bit is clear, second I/O pin affected to PSCOUT22 acts as a standard port.
When this bit is set, second I/O pin affected to PSCOUT22 is connected to the PSC waveform
generator A output and is set and clear according to the PSC operation.
• Bit 0 – POENnA: PSC n OUT Part A Output Enable
When this bit is clear, I/O pin affected to PSCOUTn0 acts as a standard port.
When this bit is set, I/O pin affected to PSCOUTn0 is connected to the PSC waveform generator
A output and is set and clear according to the PSC operation.
Note : n = 0 to 2 according to PSC number.
