(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
(3) Set the N-ch open-drain in the following sequence.
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/IF3, an on-chip pull-up resistor can be connected to the TOB0T1 to TOB0T3,
TOB0B1 to TOB0B3, and TOA21 pins, these are output pins in the alternate-function mode, when these pins
go into a high-impedance state due to the TOB0OFF, TOA2OFF, and TOB1OFF pins or software processing.
For the V850E/IG3, an on-chip pull-up resistor can be connected to the TOB0T1 to TOB0T3, TOB0B1 to
TOB0B3, TOA21, TOB1T1 to TOB1T3, TOB1B1 to TOB1B3, and TOA31 pins, these are output pins in the
alternate-function mode, when these pins go into a high-impedance state due to the TOB0OFF, TOA2OFF,
TOB1OFF, and TOA3OFF pins or software processing.
Set the on-chip pull-up resistor in the following sequence.
<1> Set PMCn register.
<2> Set PMn register.
<3> Set PU register.
• Used in port mode
<1> Set PMCn register.
<2> Set PFn register.
• Used as output pin in alternate-function mode of I
<1> Set PFCn and PFCEn registers.
<2> Set PFn register.
<3> Set PMCn register.
