Overview

Port 1 is an 8-bit I/O port. Port 1 pins also function as PPG output pins (PO15 to PO8), TPU I/O pins (TCLKA, TCLKB,
TCLKC, TCLKD, TIOCA0, TIOCB0, TIOCC0, TIOCD0, TIOCA1, TIOCB1, TIOCA2, and TIOCB2), and DMAC
output pins (DACK0 and DACK1). Port 1 pin functions are the same in all operating modes.
Figure 9-1 shows the port 1 pin configuration.
