22.8 Port G
Port G is a 3-bit special function port that shares all of its pins with the keyboard interrupt module (KBD).
Note that Port G is only available on 64-pin package options.
22.8.1 Port G Data Register
The port G data register contains a data latch for each of the three port G pins.
PTG[2:0] — Port G Data Bits
KBD[2:0] — Keyboard Wakeup pins
22.8.2 Data Direction Register G
Data direction register G determines whether each port G pin is an input or an output. Writing a logic 1 to
a DDRG bit enables the output buffer for the corresponding port G pin; a logic 0 disables the output buffer.
Freescale Semiconductor
These read/write bits are software programmable. Data direction of each port G pin is under the control
of the corresponding bit in data direction register G. Reset has no effect on PTG[2:0].
The keyboard interrupt enable bits, KBIE[2:0], in the keyboard interrupt control register, enable the port
G pins as external interrupt pins (See
interrupt pin will override the corresponding DDRGx.
