Operation
Caution:
The Z8 Encore! XP F082A Series devices feature a general purpose comparator that com-
pares two analog input signals. These analog signals may be external stimulus from a pin
(CINP and/or CINN) or internally generated signals. Both a programmable voltage refer-
ence and the temperature sensor output voltage are available internally. The output is
available as an interrupt source or can be routed to an external pin.
When the positive comparator input exceeds the negative input by more than the specified
hysteresis, the output is a logic High. When the negative input exceeds the positive by
more than the hysteresis, the output is a logic Low. Otherwise, the comparator output
retains its present value. See
The comparator may be powered down to reduce supply current. See the
Register 0
Because of the propagation delay of the comparator, Zilog does not recommend enabling
or reconfiguring the comparator without first disabling the interrupts and waiting for the
comparator output to settle. Doing so can result in spurious interrupts.
