Thermometer Reading (TR):
Provides the current counter value. The current counter value
corresponds to thermal sensor temperature if TSS
[Thermometer mode Output Valid] = 1.
This register has a straight binary encoding that will range from
0 to FFh.
Relative Temperature (RELT):
HTPS-TR. In Thermometer mode, the RELT field of this register
reports the relative temperature of the thermal sensor. Provides
a two's complement value of the thermal sensor relative to the
Hot trip point. Temperature above the Hot trip point will be
positive.
See also TSS [Thermometer mode Output Valid]
In the Analog mode, the RELT field reports HTPS value.
Aux0 Trip Point Setting (A0TPS):
Sets the target for the Aux0 trip point.
Lockable by TSTTP2-1 [31].
Hot Trip Point Setting (HTPS):
Sets the target value for the Hot trip point.
Lockable via TCO bit 7.
Catastrophic Trip Point Setting (CTPS):
Sets the target for the Catastrophic trip point.
Lockable via TCO bit 7.
