(1) Set the registers of a port in the following sequence.
(2) An on-chip pull-up resistor can only be connected when the pins are in input mode in the port mode, or when
Cautions
<1> Set PFCn and PFCEn registers.
<2> Set PMCn register.
<3> Set INTFn and INTRn registers.
If the PMCn register is set before setting the PFCn and PFCEn registers, an unexpected peripheral function
may be selected while the PFCn and PFCEn registers are being set.
the pins function as input pins in the alternate-function mode.
Moreover, for the V850E/IA3, an on-chip pull-up resistor can be connected to the TOQ0T1 to TOQ0T3,
TOQ0B1 to TOQ0B3, and TOP21 pins, these are output pins in the alternate-function mode, when these pins
go into a high-impedance state due to the TOQ0OFF and TOP2OFF pins or software processing.
For the V850E/IA4, an on-chip pull-up resistor can be connected to the TOQ0T1 to TOQ0T3, TOQ0B1 to
TOQ0B3, TOP21, TOQ1T1 to TOQ1T3, TOQ1B1 to TOQ1B3 and TOP31 pins, these are output pins in the
alternate-function mode, when these pins go into a high-impedance state due to the TOQ0OFF, TOP2OFF,
TOQ1OFF, or TOP3OFF pin or software processing.
