Section 9 I/O Ports
9.8
Port A is an 8-bit I/O port and has the following registers.
• 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)
9.8.1
PADDR specifies input or output the port A pins using the individual bits. PADDR cannot be
read; if it is, the read value is undefined. Since this register is a write-only register, bit-
manipulation instructions should not be used when writing. See section 2.9.4, Access Method for
Registers with Write-only Bits.

Description
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.
