6.1 Overview
In single-chip mode (mode 3), the H8/325 Series chips can interface to another device by parallel
handshaking, using port 3.
6.1.1 Features
• Built-in latch circuits
• Strobe signal output
• Busy signal output
• Input strobe interrupt
• Recovery from software standby mode
Data input to port 3 can be latched on the falling edge of the IS signal.
A strobe signal can be output on the OS line when port 3 is written or read.
A busy signal is output on the BUSY line from the time when data are latched on the falling edge
of IS until the latched data are read, unlocking the latch.
An input strobe interrupt can be generated at the falling edge of the IS signal.
The input strobe interrupt can be used to recover from software standby mode.
