Safety Overtemperature EE 0x09 sets Safety Overtemperature Threshold (SOT) level for the CFC pin. It can be
programmed for a threshold of 69°C to 94.5°C. This range is increased by 16°C if Miscellaneous Options
bit 5 = 1.
Safety Overtemperature = (94.5 – SOT)*10
if Miscellaneous Options bit 5 = 0.
Safety Overtemperature = (110.5 – SOT)*10
if Miscellaneous Options bit 5 = 1.
Miscellaneous Options
Miscellaneous Options EE 0x08 contains bit-programmable options. Bits 0–4 should be programmed to zero.

The NE1 bit disables the EDV1 threshold.
0 EDV1 enabled
1 EDV1 disabled
SOT
The SOT bit controls override of the CFC pin for Safety Overtemperature threshold.
0 CFC control with overvoltage, maximum temperature, and safety overtemperature.
1 CFC control; only with safety overtemperature.
HIT
The HIT bit controls the available temperature range for maximum temperature and Safety Overtemperature.
0 Maximum temperature set in normal 45°C–69°C range and Safety Overtemperature is 69°C – 94.5°C.
1 Maximum temperature set in elevated 61°C–85°C range and Safety Overtemperature is 85°C – 110.5°C.
Cycle Count Initialization
Cycle Count EE 0x0e–0x0f stores the initial value for the CycleCount() function. It should be programmed to
0x0000.
Control Modes
Control Mode EE0x51 contains additional bit programmable features.
