Section 17 I/O Ports (I/O)
17.1 Overview
The SH7050 series has eight ports: A, B, C, D, E, F, G, and H.
Ports A to G are input/output ports (A: 16 bits, B: 12 bits, C: 15 bits, D: 16 bits, E: 15 bits, F: 12
bits, G: 16 bits), and H is a 16-bit input port.
All the port pins are multiplexed as general input/output pins (general input pins in the case of port
H) and special function pins. The functions of the multiplex pins are selected by means of the pin
function controller (PFC). Each port is provided with a data register for storing the pin data.
17.2 Port A
Port A is an input/output port with the 16 pins shown in figure 17.1.
