Section 9 I/O Ports
Port A MOS Pull-Up Control Register (PAPCR) [H8S/2351 Only]
PAPCR is an 8-bit readable/writable register that controls the MOS input pull-up function
incorporated into port A on an individual bit basis.
All the bits are valid in modes 1 to 3, 6, and 7, and bits 7 to 5 are valid in modes 4 and 5. When a
PADDR bit is cleared to 0 (input port setting), setting the corresponding PAPCR bit to 1 turns on
the MOS input pull-up for the corresponding pin.
PAPCR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its
prior state after a manual reset, and in software standby mode.
Port A Open Drain Control Register (PAODR) [H8S/2351 Only]
PAODR is an 8-bit readable/writable register that controls whether PMOS is on or off for each
port A pin (PA
All bits are valid in modes 1 to 3, and 7.
Setting a PAODR bit to 1 makes the corresponding port A pin an NMOS open-drain output, while
clearing the bit to 0 makes the pin a CMOS output.
PAODR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its
prior state after a manual reset, and in software standby mode.
