User defined groups
For a keypad scan matrix, the voice groups are listed in the following table for quick reference. Each key is
composed of the connection of a trigger (TG1 - TG4) and a ground source (VSS, IO1 - IO7). Upon depression
of a key, the trigger input senses a low pulse during a H/W scan period to determine which key is pressed. In
order to avoid possible ambiguities during multiple key depressions, only falling edge triggers are allocated for
keypad applications. Rising edge triggers are only available for direct trigger pins, i.e. TG1 - TG4.

(NA) except for direct triggers to avoid possible ambiguities in keypad scan applications by H/W.
