I/O Ports
The MCU has 53 input/output pins (D

–D
13
, R0

–R9
3
) and one input-only pin (RA
1
).
The 30 pins consisting of ports D
0
–D
13
, R1, R2, R8, and R9 are all high-voltage I/O pins. RA
1
is a high-
voltage input-only pin. The high-voltage pins can be equipped with or without pull-down resistance, as
selected by the mask option.
All standard voltage output pins are CMOS output pins. However, the R0
2
/SO pin can be programmed
for NMOS open-drain output.
In stop mode, input/output pins go to the high-impedance state.
All standard voltage input/output pins have pull-up MOS built in, which can be individually turned on
or off by software (Table 5).
Pull-up MOS on/off settings can be made independently of settings as on-chip supporting module pins.
