Input/Output
The MCU has 42 input/output pins (D

–D

–R7
3
) and 2 input pins (D
10
, D
11
). The features are
described below.
Ten pins (D

) are high-current input/output pins.
The D

input/output pins are multiplexed with peripheral function pins such as
for the timers or serial interface. For these pins, the peripheral function setting is done prior to the D or
R port setting. Therefore, when a peripheral function is selected for a pin, the pin function and
input/output selection are automatically switched according to the setting.
Input or output selection for input/output pins and port or peripheral function selection for multiplexed
pins are set by software.
Peripheral function output pins are CMOS output pins. Only the R2
3
/SO pin can be set to NMOS open-
drain output by software.
In stop mode, the MCU is reset, and therefore peripheral function selection is cancelled. Input/output
pins are in high-impedance state.
Each input/output pin has a built-in pull-up MOS, which can be individually turned on or off by
software.
I/O buffer configuration is shown in figure 29, programmable I/O circuits are listed in table 17, and I/O pin
circuit types are shown in table 18.
