Description
Power supply pin. Connect it to the system power supply.
Connect this pin to the VSS pin via the 0.1 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 resonator. An external clock signal can
be input through the EXTAL pin.
Input/output pins for the sub-clock generation circuit. Connect a
crystal resonator between XCIN and XCOUT.
Pin for setting the operating mode. The signal levels on this pin
must not be changed during operation.
Reset signal input pin. This LSI enters the reset state when this
signal goes low.
Input pin for the measuring circuit for clock frequency precision.
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 TGRA1 and TGRB1 input capture input/output compare output/
PWM output pins.
The TGRA2 and TGRB2 input capture input/output compare output/
PWM output pins.
The TGRA3 to TGRD3 input capture input/output compare output/
PWM output pins.
The TGRA4 to TGRD4 input capture input/output compare output/
PWM output pins.
The TGRU5, TGRV5, and TGRW5 input capture input/external
pulse input pins.
Input pins for external clock.
Input pins for request signals to place the MTU pins in the high
impedance state.
Compare match output pins.
Input pins for external clocks to be input to the counter.
Input pins for the counter reset.
Output pin for 1-Hz clock.
