10B.5 Port 7
10B.5.1 Overview
Port 7 is an 8-bit I/O port. Port 7 is a multipurpose port for the bus control output pins (CS4 to
CS7), SCI I/O pins (SCK3, RxD3, and TxD3), and manual reset input pin (MRES). The pin
functions for P77 to P74 are the same in all operating modes. P73 to P70 pin functions are
switched according to operating mode.
Figure 10B.4 shows the configuration for port 7 pins.
