4.3.2
The TCN75A has a 16-bit read/write Temperature
Limit-Set register (T
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 4.3.4.3 “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 T
80°C, or <0 1010 0000> in binary.
