TCN75A
5.3.4 TEMPERATURE LIMIT-SET
REGISTER (TSET)
The TCN75A has a 16-bit read/write Temperature
Limit-Set register (TSET) which contains a 9-bit data in
two’s compliment format. This data represents a maxi-
mum temperature limit. If the ambient temperature
exceeds this specified limit, the TCN75A asserts an
alert output. (Refer to Section 5.3.4.3 “ALERT Output
Configuration”).
This register uses the nine Most Significant bits (MSbs)
and all other bits are “don’t cares”.
The power-up default value of the TSET register is
80°C, or <0101 0000 0>b in binary.
