The operation guaranteed range is 1.8 V ≤ V
when the supply voltage falls, use the reset function of the low-voltage detector, or input the low level to the
RESET pin.
The internal high-speed oscillation clock and a high-speed system clock or subsystem clock can be
selected as the CPU clock. To use the X1 clock, use the oscillation stabilization time counter status register
(OSTC) to confirm the lapse of the oscillation stabilization time. To use the XT1 clock
function for confirmation of the lapse of the stabilization time.
The internal reset processing time includes the oscillation accuracy stabilization time of the internal high-
speed oscillation clock.
The following times are required between reaching the POC detection voltage (1.61 V (TYP.)) and starting
normal operation.
• When the time to reach 2.07 V (TYP.) from 1.61 V (TYP.) is less than 5.8 ms:
• When the time to reach 2.07 V (TYP.) from 1.61 V (TYP.) is greater than 5.8 ms:
The 78K0R/KC3-L (40-pin) doesn’t have the subsystem clock.
