NOTES:
• Key number "#" is located on GenIO13 with interrupt on GenIOInt1. RH-53 Mar-
keting accept the reduction in performance when there is no wake up from deep
sleep.
• Power on/off and End Call are combined. For ending call: "short" keypress. For
power off: "Long" keypress
All lines are configured as input, when there is no key pressed; the inputs are high due to that
the UPP has internally pull-up resistors on those lines. When a key is pressed, the specific line
where the key is placed is pulled low. This generates an interrupt to the MCU and the MCU now
starts its scanning procedure.
