I/O Port
(1) Overview
General-purpose (parallel) I/O ports can be used as the I/O ports. The MB90495G Series has 7 ports (49) .
Each port doubles as a peripheral device I/O pin.
I/O Port Features
I/O ports output data to I/O pins and load signals input to them, by means of the port data register (PDR) .
Additionally, the port direction register (DDR) sets the I/O direction of the I/O pins at the bit level. Below is a
description of each pin’s function, and the peripheral device that shares it.
Port 0 : general-purpose I/O port/doubles as external address data bus pin
Port 1 : general-purpose I/O port/doubles as PPG timer output, input capture input, and external address data
bus pin
Port 2 : general-purpose I/O port/doubles as reload timer I/O, external interrupt input pin, and external address
bus pin
Port 3 : general-purpose I/O port/doubles as UART0 I/O, free-run timer, and A/D converter startup trigger pin
Port 4 : general-purpose I/O port/doubles as UART1 I/O, and CAN controller transmit/receive pin
Port 5 : general-purpose I/O port/doubles as analog input pin
Port 6 : general-purpose I/O port/doubles as external interrupt input pin
