9.2 Port 1
9.2.1 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.
