Serial clock: Clock I/O pins.
The SCK0 output type is NMOS push-pull.
Transmit data: Data output pins.
Receive data: Data input pins.
Serial clock: Clock I/O pins.
The SCK0 output type is NMOS push-pull.
HCAN transmit data. Pin for CAN bus transmission.
HCAN receive data. Pin for CAN bus reception.
Analog 11 to 0: Analog input pins.
A/D conversion external trigger input: Pin for input of
an external trigger to start A/D conversion.
Analog power supply: A/D converter power supply pin.
If the A/D converter is not used, connect this pin to the
system power supply (+5 V).
Analog ground: Analog circuit ground and reference
voltage. Connect this pin to the system power supply
(0 V).
Analog reference power supply: A/D converter
reference voltage input pin. If the A/D converter is not
used, connect this pin to the system power supply
(+5 V).
PWM output: Motor control PWM channel 1 output pins
PWM output: Motor control PWM channel 2 output pins
