15. I/O Ports

■ List of port registers

R/W

: Readable/writable (The read value is the same as the write value.)

R, RM/W : Readable/writable (The read value is different from the write value. The write value is read by the read-modify-write

(RMW) type of instruction.)

15.1 Port 0

Port 0 is a general-purpose I/O port. This section focuses on its functions as a general-purpose I/O port. For details of peripheral

functions, refer to their respective chapters in “New 8FX MB95610H Series Hardware Manual”.

15.1.1 Port 0 configuration

Port 0 is made up of the following elements.

■ General-purpose I/O pins/peripheral function I/O pins

■ Port 0 data register (PDR0)

■ Port 0 direction register (DDR0)

■ A/D input disable register (lower) (AIDRL)
