2 POWER SUPPLY
2.3 Heavy Load Protection Mode
The S1C88816 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 periph-
eral circuits are in the following status:
(1) When the OSC3 oscillation circuit is ON
(OSCC = "1" and not in SLEEP)
(2) When the buzzer output is ON
(BZON = "1" or BZSHT = "1")
(3) When the melody output is ON
(MBUSY = "1")
The conditions (2) and (3) can be selected by mask
option.

When direct driving a piezoelectric buzzer with the
buzzer (BZ, BZ) or melody signal (MOUT, MOUT),
select Normal mode to reduce current
consumption. When driving an external bipolar
transistor with the BZ or MOUT signal, select
Heavy load protection mode.
When using the melody output terminal (MOUT,
MOUT) for buzzer output, select the same option
for both the buzzer and melody outputs.
For details of the OSC3 oscillation circuit, buzzer
output and melody output, refer to "5.3 Oscillation
Circuits and Operating Mode", "5.12 Sound
Generator" and "5.13 Melody Generator",
respectively.
