Section 9 I/O Ports
Rev.4.00 Sep. 18, 2008 Page 285 of 872
REJ09B0189-0400
9.2
Port 1
9.2.1
Overview
Port 1 is an 8-bit I/O port. Port 1 pins also function as TPU I/O pins (TCLKA, TCLKB, TCLKC,
TCLKD, TIOCA0, TIOCB0, TIOCC0, TIOCD0, TIOCA1, TIOCB1, TIOCA2, and TIOCB2),
external interrupt pins (
IRQ0 and IRQ1), and address bus output pins (A23 to A20). Port 1 pin
functions depend on the operating mode.
The interrupt input pins (
IRQ0 and IRQ1) are Schmitt-triggered inputs.
Figure 9.1 shows the port 1 pin configuration.
