Section 24 I/O Ports
SH7243 has six ports: A, B, C, D, E, and F. Port A is an 8-bit, port B is a 7-bit, ports C to E are
16-bit I/O ports, and port F is an 8-bit input-only port.
SH7285 has six ports: A, B, C, D, E, and F. Port A is a 17-bit, port B is an 11-bit, port C is a 16-
bit, port D is a 32-bit and port E is a 16-bit I/O port, and port F is an 8-bit input-only port.
SH7286 has six ports: A, B, C, D, E, and F. Port A is a 19-bit, port B is an 18-bit, port C is a 16-
bit, port D is a 32-bit and port E is a 16-bit I/O port, and port F is a 12-bit input-only port.
All port pins are multiplexed with other pin functions. The functions of the multiplex pins are
selected by means of the pin function controller (PFC). Each port is provided with data registers
for storing the pin data.
