8.6
In the H8S/2218 Group, the port A is a 4-bit I/O port also functioning as address bus (A19 to A16)
output pins and SCI I/O pins. In the H8S/2212 Group, the port A is a 3-bit I/O port also
functioning as SCI I/O pins. The port A 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)
8.6.1
PADDR specifies input or output for the pins of the port A.
Since PADDR is a write-only register, the bit manipulation instructions must not be used to write
PADDR. For details, see section 2.9.4, Accessing Registers Containing Write-Only Bits.

Modes 4 to 6:
If address output is enabled by the setting of bits AE3 to
AE0 in PFCR, the corresponding port A pins are address
outputs. When address output is disabled, setting a
PADDR bit to 1 makes the corresponding port A pin an
output port, while clearing the bit to 0 makes the pin an
input port.
Mode 7:
Setting a PADDR bit to 1 makes the corresponding port A
pin an output port, while clearing the bit to 0 makes the
pin an input port.
(H8S/2212 Group)
Setting a PADDR bit to 1 makes the corresponding port A
pin an output port, while clearing the bit to 0 makes the
pin an input port.
