17. I/O Ports (I/O)
17.1 Overview
The SH7016 and SH7017 have six ports, A to F, and the SH7014 has four ports, A, B, E, and F.
The pins of the ports are multiplexed for use as general-purpose I/Os (the port F pins are general
input) or for other functions. Use the pin function controller (PFC) to select the function of
multiplexed pins. The ports each have one data register for storing pin data. The initialize function
after power-on reset differs depending on the operating mode of each pin. See tables 16.2 and
16.3, Pin Arrangement by Mode, for details.
17.2 Port A
Port A is a 16-pin input/output port (11-pin in the SH7014) as shown in table 17.1.
