8.2 Port 1
8.2.1 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) and
an address bus output function. Port 1 pin functions change according to the operating mode.
Figure 8.1 shows the port 1 pin configuration.
