Signal Description
The following paragraphs provide a description of the signals.
1.5.1 V
DD
and V
SS
Power is supplied to the microcontroller through VDD and VSS. VDD is the power
supply and VSS is ground.
1.5.2 IRQ
This pin has a mask option that provides two different choices of interrupt
triggering sensitivity. The IRQ pin contains an internal Schmitt trigger as part of its
input to improve noise immunity. Refer to SECTION 3 CENTRAL PROCESSING
UNIT for more detail.
