OSC1 = 32.768 kHz crystal oscillation, CG = 25pF, OSC3 = External clock input, Non heavy load protection mode,
C1 = C2 = C3 = C4 = C5 = C6 = C7 = C8 = C9 = 0.1
F, No panel load
OSC1: Stop,
OSC1: Oscillating,
SC1: Oscillating,
It is the value of current which flows in the heavy load protection circuit when in the heavy load protection mode
(OSC3 ON or buzzer ON).
The value in x V can be found by the following expression: ISVDN (VDD = x V) = (x
× 20) - 30 (Typ. value),
ISVDN (VDD = x V) = (x
× 30) - 30 (Max. value)
When OSC1 CR oscillation circuit is selected by the mask option.
