21.2.4 Using H8S/2357 I/O Ports
In the interface circuit of
purpose output port. This pin drives the ISP1181B’s WAKEUP input to generate a remote
wake-up.
The H8S/2357 has 3 registers to configure port 1: Port 1 Data Direction Register
(P1DDR), Port 1 Data Register (P1DR) and Port 1 Register (PORT1). Only registers
P1DDR and P1DR must be configured, register PORT1 is only used to read the actual
levels on the port pins.
The dynamic characteristics of the analog I/O ports (D+ and D ) as listed in
were determined using the circuit shown in
Fig 33. Load impedance for D+ and D pins.
•
H8S/2357:
– select pin P1.1 to be an output in register P1DDR
– program the desired bit value for P1.1 in register P1DR.
