The group of this LSI has twenty-nine general I/O ports (twenty-seven general I/O ports in the
H8/3694N) and eight general input-only ports. Port 8 is a large current port, which can drive 20
mA (@V
port immediately after a reset. They can also be used as I/O pins of the on-chip peripheral modules
or external interrupt input pins, and these functions can be switched depending on the register
settings. The registers for selecting these functions can be divided into two types: those included
in I/O ports and those included in each on-chip peripheral module. General I/O ports are
comprised of the port control register for controlling inputs/outputs and the port data register for
storing output data and can select inputs/outputs in bit units. For functions in each port, see
appendix B.1, I/O Port Block Diagrams. For the execution of bit manipulation instructions to the
port control register and port data register, see section 2.8.3, Bit Manipulation Instruction.

Port 1 is a general I/O port also functioning as IRQ interrupt input pins, a timer A output pin, and
a timer V input pin. Figure 9.1 shows its pin configuration.
Port 1 has the following registers.
Port mode register 1 (PMR1)
Port control register 1 (PCR1)
Port data register 1 (PDR1)
Port pull-up control register 1 (PUCR1)
