28.1
This LSI has sixteen general-purpose ports (A to H, J to N, and P to R), which provide 111
input/output pins.
The general-purpose I/O (GPIO) port pins are multiplexed with the pins of peripheral modules to
select whether the pins are used by the GPIO or the peripheral modules.
The GPIO has the following features.
• Each port pin is a multiplexed pin, for which the port control register can specify the pin
• Each port has a data register that stores data for the pins.
• GPIO interrupts are supported
Note:
function and control the pull-up MOS of the pin.
*
Features
For the ports which can be used as GPIO interrupt pins, refer to table 28.1. For GPIO
interrupt settings, refer to section 10, Interrupt Controller (INTC).
