allowing certain keys to be masked from detection.
Tables 18–21 show the programmable bits of the keypad
control register. Tables 23, 24, and 25 show the program-
mable bits of the keypad mask registers. The
Keypad
Controller and GPIO section provides more details.
GPIO Control Register
The GPIO control register and the GPIO pullup register
allow the keypad controller’s row and column inputs to be
configured as up to eight parallel I/O pins. Tables 26 and
27 show the GPIO control register layout and control reg-
ister descriptions. Tables 28 and 29 show the GPIO pullup
disable register and associated descriptions. For more
information, see the
Applications Information section.
