PCR2 to PCRP execute pull-up resistor control for the corresponding I/O port.
•
PCR = 0: Without pull-up resistor
•
PCR = 1: With pull-up resistor
PJ0 to PJ7, PK0 to PK7, and PL0 and PL1 do not have a pull-up resistor.
*: The MB91F353A/351A/352A/353A do not have PCRs that are PCRB, PCRC, PCRG, and PCRP. Also,
the bit values of P65, P66, P67, P92, PN1, PN3, PN5, P01, P03, P04, P05, P06, and P07 are invalid.
