These bits are unused and always set to 0
Rewriteable register
These bits are unused and always set to 0
Lookup table hysteresis. (Default 4°C ; 1LSB = 1°C)
This bit is unused and always set to 0
When T2 (external) temperature exceeds (greater than) this value, PWM output will be
the value of INDEX 5(y)h register.
These bits are unused and always set to 0
PWM output value corresponds to the temperature entry in INDEX 5(x)h.
