9.4
Port A is a 4-bit I/O port that also has other functions. Port A has the following registers. For
details on register addresses and register states during each processing, refer to appendix A, On-
Chip I/O Register.
• Port A data direction register (PADDR)
• Port A data register (PADR)
• Port A register (PORTA)
• Port A pull-up MOS control register (PAPCR)
• Port A open-drain control register (PAODR)
9.4.1
PADDR is an 8-bit write-only register, the individual bits of which specify whether the pins of
port A are used for input or output. PADDR cannot be read; if it is, an undefined value will be
read.

Reserved
When a pin is specified as a general purpose I/O
port, setting this bit to 1 makes the corresponding
port A pin an output pin. Clearing this bit to 0 makes
the pin an input pin.
