CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Heavy Load Protection Function)
4.15 Heavy Load Protection Function
4.15.1 Outline of heavy load protection function
The S1C60N13 Series has the heavy load protection function for when the battery load becomes heavy
and the source voltage changes, such as when an external buzzer sounds or an external lamp lights.
The state where the heavy load protection function is in effect is called the heavy load protection
mode. Compared with the normal operation mode, this mode can reduce the output voltage variation
of the constant voltage.
The normal mode changes to the heavy load protection mode in the following case:
When the software changes the mode to the heavy load protection mode (HLMOD = "1")
The heavy load protection mode switches the voltage regurator circuit to the high-stability mode from
the low current consumption mode. Consequently, more current is consumed in the heavy load
protection mode than in the normal mode. Unless it is necessary, be careful not to set the heavy load
protection mode with the software.
4.15.2 Control of heavy load protection function
Table 4.15.2.1 shows the control bits and their addresses for the heavy load protection function.

HLMOD: Heavy load protection mode (2E6HD3)
Sets the IC in heavy load protection mode.
When "1" is written : Heavy load protection mode is set
When "0" is written : Heavy load protection mode is released
Read-out : Valid
When HLMOD is set to "1", the IC enters the heavy load protection mode.
4.15.3 Programming note
More current is consumed in the heavy load protection mode than in the normal mode. Unless it is
necessary, be careful not to set the heavy load protection mode with the software.
