(a) REGC
This is a pin for connecting regulator output (2.0 V/2.4 V) stabilization capacitance for internal operation. Connect
this pin to V
SS via a capacitor (0.47 to 1 μ F). However, when using the STOP mode that has been entered since
operation of the internal high-speed oscillation clock and external main system clock, 0.47
μ F is recommended.
Also, use a capacitor with good characteristics, since it is used to stabilize internal voltage.

Caution Keep the wiring length as short as possible for the broken-line part in the above figure.
(b) IC0
This is an internally connected pin. Connect directly to V
SS.
(c) IC
This is an internally connected pin. Leave open.
