TIP #6 Scanning Many Keys and
Wake-up From Sleep
An additional I/O can be added to wake the part
when a button is pressed. Prior to sleep, configure
GP1 as an input with interrupt-on-change enabled
and GP2 to output high. The pull-down resistor
holds GP1 low until a button is pressed. GP1 is
then pulled high via GP2 and V
DD generating an
interrupt. After wake-up, GP2 is configured to
output low to discharge the capacitor through the
220 Ohm resistor. GP1 is set to output high and
GP2 is set to an input to measure the capacitor
charge time.
GP1 pin connected to key common
Enable wake-up on port change
Set GP1 as input and GP2 high prior to sleep
If key is pressed the PIC MCU wakes up, GP2
must be set low to discharge capacitor
Set GP1 high upon wake-up to scan keystroke
