General Description
MOTOROLA
Figure 1-6. 44-Pin QFP Pin Assignments
NOTE:
If MC68HC705C9A devices are to be used in the same socket, pin 43
should be tied to V
DD
.
1.6.1 V
DD
and V
SS
Power is supplied to the MCU using these two pins. V
DD
is the positive
supply and V
SS
is ground.
1.6.2 IRQ
This interrupt pin has an 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 4.
