Product Specification
Timers
There are two independent and identical 16 bit multi-function timers available – Timer 0 and
Timer 1.
Timer 0
This timer is available to the user application.
8 Pin Device: T0OUT not available in Dual Pyro Mode – configured as ANA3 to support
second sensor input. All other external Timer 0 functions are available for the user application.
20 Pin Device: All external Timer 0 functions are available for the user application.
28 Pin Device: All external Timer 0 functions are available for the user application.
Timer 1
This timer is available to the user application.
8 Pin Device: T1IN is configured as ANA2 to support the signal input from the pyroelectric
sensor and is not available to the user application. All other Timer 1 functions are available.
20 Pin Device: All external Timer 1 functions are available for the user application.
28 Pin Device: All external Timer 1 functions are available for the user application.
Watchdog Timer
No changes or limitations are placed on these functions by Zilog’s PIR technology. This is
available to the user application.
Comparator
8 Pin Device: The external pin that carries COUT is configured as ANA2 to support the signal
input from the Pyroelectric sensor. However, the Comparator is still able to generate an
interrupt internally without COUT.
20 Pin Device: All external Comparator functions are available for the user application.
28 Pin Device: All external Comparator functions are available for the user application.
