Description
Power supply pin. Connect it to the system power supply.
Connect this pin to the VSS pin via the 4.7 μF smoothing capacitor used to
stabilize the internal power supply. Place the capacitor close to the pin.
Ground pin. Connect it to the system power supply (0 V).
Pins for connecting a crystal. An external clock can be input through the
EXTAL pin.
Pin for setting the operating mode. The signal levels on this pin must not
be changed during operation.
Reset pin. This MCU enters the reset state when this signal goes low.
Input pin for the clock frequency accuracy measurement circuit.
FINE interface pin.
Non-maskable interrupt request pin.
Interrupt request pins.
The TGRA0 to TGRD0 input capture input/output compare output/PWM
output pins.
The TGRA0 to TGRD0 input capture inverted input/output compare
inverted output/PWM inverted output pins.
The TGRA1 and TGRB1 input capture input/output compare output/PWM
output pins.
The TGRA1 and TGRB1 input capture inverted input/output compare
inverted output/PWM inverted output pins.
The TGRA2 and TGRB2 input capture input/output compare output/PWM
output pins.
The TGRA2 and TGRB2 input capture inverted input/output compare
inverted output/PWM inverted output pins.
The TGRA3 to TGRD3 input capture input/output compare output/PWM
output pins.
The TGRA3 to TGRD3 input capture inverted input/output compare
inverted output/PWM inverted output pins.
The TGRA4 to TGRD4 input capture input/output compare output/PWM
output pins.
The TGRA4 to TGRD4 input capture inverted input/output compare
inverted output/PWM inverted output pins.
The TGRU5, TGRV5, and TGRW5 input capture input/external pulse input
pins.
The TGRU5, TGRV5, and TGRW5 input capture inverted input/external
pulse inverted input pins.
The TGRA6 to TGRD6 input capture input/output compare output/PWM
output pins.
The TGRA6 to TGRD6 input capture inverted input/output compare
inverted output/PWM inverted output pins.
The TGRA7 to TGRD7 input capture input/output compare output/PWM
output pins.
The TGRA7 to TGRD7 input capture inverted input/output compare
inverted output/PWM inverted output pins.
The TGRA9 to TGRD9 input capture input/output compare output/PWM
output pins.
