General Description
General Release Specification
MC68HC05C9A Rev. 4.0
General Description
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 VDD.
1.6.1 VDD and VSS
Power is supplied to the MCU using these two pins. VDD is the positive
supply and VSS 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.
Interrupts for more detail.
