Section 10 I/O Ports
10.6
Port A is a 4-bit I/O port and has the following 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)
10.6.1
PADDR specifies input or output the port A pins using the individual bits. PADDR cannot be
read; if it is, an undefined value will be read. This register is a write-only register, and cannot be
written by bit manipulation instruction. For details, see section 2.9.4, Access Methods for
Registers with Write-Only Bits.
10.6.2
PADR stores output data for port A pins.

Description
Reserved
These bits are always read as undefined value.
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.
Description
Reserved
These bits are always read as undefined value.
Output data for a pin is stored when the pin is
specified as a general purpose output port.
