TCN75A
4.3.3
The TCN75A has a 16-bit read/write Temperature
Hysteresis register that contains a 9-bit data in two’s
compliment format. This register is used to set a
hysteresis for the T
represents a minimum temperature limit. If the ambient
temperature drifts below the specified limit, the

This register uses the nine Most Significant bits (MSbs)
and all other bits are don’t cares.
