2.3 Heavy Load Protection Mode

The E0C88832/88862 has a heavy load protection
function for stable operation even when the supply
voltage fluctuates by driving a heavy load. The
heavy load protection mode becomes valid when
the peripheral circuits are in the following status:
(1) The OSC3 oscillation circuit is switched ON
(OSCC = "1" and not in SLEEP)
(2) The buzzer output is switched ON
(BZON = "1" or BZSHT = "1")
