Section 10 I/O Port
10.6 Port 4
10.6.1 Overview
Port 4 is an 8-bit I/O port. Table 10.14 shows the port 4 configuration.
Port 4 consists of pins that are used both as standard I/O ports (P47 to P40) and output compare
output (FTOA, FTOB), input capture input (FTIA, FTIB, FTIC, FTID) or 14-bit PWM output
(PWM14). It is switched by port mode register 4 (PMR4), timer output compare control register
(TOCR), and port control register 4 (PCR4).
