Input/Output
The MCU has 53 input/output pins (D
0
–D
13
, R0–R9) and an input pin (RA
1
). The features are described
below.
Eight pins (R1–R2) are high-current (15 mA max) input/output with intermediate voltage NMOS open
drain pins.
The D
0
–D
4
, R0, R3–R5 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 R0
2
/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 except for R1 and R2 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 26, programmable I/O circuits are listed in table 21, and I/O pin
circuit types are shown in table 22.
