16. RESET FUNCTION
16.1 EXTERNAL RESET
The RESET pin should be held at low for at least 2machine
cycles with the power supply voltage within the operating
voltage range and must be connected 0.1uF capacitor for
stable system initialization. The RESET pin contains a
Schmitt trigger with an internal pull-up resistor.
16.2 POWER ON RESET
Power On Reset circuit automatically detects the rise of
power voltage (the rising time should be within 50ms) the
power voltage reaches a certain level, RESET terminal is
maintained at “L” Level until a crystal ceramic oscillator
oscillates stably. After power applies and starting of oscil-
lation, this reset state is maintained for about oscillation
cycle of 219 (about 65.5ms : at 4MHz).The execution of
built-in Power On Reset circuit is as follows :
(1) Latch the pulse from Power On Detection Pulse Gener-
ator circuit, and reset Prescaler, B.I.T and B.I.T Overflow
detection circuit.
(2) Once B.I.T Overflow detection circuit is reset. Then,
Prescaler starts to count.
(3) Prescaler output is inputted into B.I.T and PS10 of
Prescaler output is automatically selected. If overflow of
B.I.T is detected, Overflow detection circuit is set.
4) Reset circuit generates maximum period of reset pulse
from Prescaler and B.I.T
