Functional Pin Descriptions
MC68HC705C9A — Rev. 2.0
General Description
Figure 1-8. 44-Pin QFP Pin Assignments
1.7.1 VDD and VSS
Power is supplied to the MCU using these two pins. VDD is the positive
supply and VSS is ground.
1.7.2 VPP
This pin provides the programming voltage to the EPROM array. For
normal operation, VPP should be tied to VDD.
1.7.3 IRQ
This interrupt pin has an option that provides two different choices of
interrupt triggering sensitivity. The IRQ pin contains an internal Schmitt
