Note: P00–P03 are measured when the P00–P03 output structure selection bit (bit 0 of PCTL1) is “0”.

P04–P07 are measured when the P04–P07 output structure selection bit (bit 1 of PCTL1) is “0”.

P10–P13 are measured when the P10–P13 output structure selection bit (bit 2 of PCTL1) is “0”.

P14–P17 are measured when the P14–P17 output structure selection bit (bit 3 of PCTL1) is “0”.

P42, P43, P44, and P46 are measured when the P4 output structure selection bit (bit 2 of PCTL2) is “0”.

P45 is measured when the P45/TXD P-channel output disable bit (bit 4 of UARTCON) is “0”.
