General Description
Table 1-1. Pin Functions
Power supply input to the MCU.
Power supply ground.
Power supply input for analog circuits.
Power supply ground for analog circuits.
Crystal connections to the on-chip oscillator.
An external clock can be connected directly to
OSC1; with OSC2 floating.
See
External reset pin; active low; with internal pull-up
and schmitt trigger input. It is driven low when any
internal reset source is asserted.
See
(SIM).
External IRQ pin; with schmitt trigger input and
internal pull-up. This pin is also used for mode
entry selection.
See
Section 9. System Integration Module
External filter capacitor connection for the CGM
module.
See
Vsync input to the sync processor.
This pin is rated at +5V.
See
Hsync input to the sync processor.
This pin is rated at +5V.

These are shared function, bidirectional I/O port
pins. Each pin contains a pull-up device to VDD
when it is configured as an external keyboard
interrupt pin.
