Name and Function
Port F: A 6-bit I/O port. Input or output can be
designated for each bit by means of the port F data
direction register (PFDDR).
Port H: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port B data
direction register (PHDDR).
Port J: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port J data
direction register (PJDDR).
PWM output: Motor control PWM channel 1 output
pins.
PWM output: Motor control PWM channel 2 output
pins.
PWM Power Supply: Power supply pin for motor-
control PWM.
Connect to the system power supply (+5 V) when the
motor-control function is not used.
PWM Ground: Ground pin for motor-control PWM.
Connect to the system power supply (0 V).
I
input/output pins that have bus-driving capability. The
output of SCL0 is an NMOS open-drain type.
I
input/output pins that have bus-driving capability. The
output of SDA0 is an NMOS open-drain type.
