GPI Input
Each of the 19 I/O lines can be configured as a general-purpose
logic input line. Figure 17 shows a detailed representation of the
GPI scan and detect block and all its associated control and
status signals.

Figure 17. GPI Scan and Detect Block
The current input state of each GPI can be read back using the
GPI_STATUS_x registers. Each GPI can be programmed to
generate an interrupt via the GPI_INTERRUPT_EN_x registers.
The interrupt status is stored in the GPI_INT_STAT_x registers.
GPI interrupts can be programmed to trigger on inputs being
high or on inputs being low via the GPI_INT_LEVEL_x
registers. If any of the GPI interrupts is triggered, the master
GPI_INT interrupt is also triggered.
Figure 18 demonstrates a single GPI and how it affects its
corresponding status and interrupt status bits.

Figure 18. Single GPI Example
GPIs can be programmed to generate FIFO events via the
GPI_EVENT_EN_x registers. GPIs in this mode do not gener-
ate GPI_INT interrupts and instead generate EVENT_INT
interrupts. Figure 19 shows several GPI lines and their effects
on the FIFO and event count, EC[4:0].

Figure 19. Multiple GPI Lines Example
The GPI scanner is idle until it detects a level transition. It scans
the GPI inputs and updates accordingly. It then returns to idle
immediately; it does not scan/wait, like the key scanner. As
such, the GPI scanner can detect narrow pulses once they get
past the 50 μs input debounce filter.
GPIs (programmed for FIFO updating) can be used as keypad
unlock events via the UNLOCKx registers (see the FIFO
Lock/Unlock section). The LCK_TRK_GPI bit can be used to
allow GPIs (programmed for FIFO updating) to be tracked
when the keypad is locked.
GPO OUTPUT
Each of the 19 I/O lines can be configured as a general-purpose
output (GPO) line. Figure 6 shows a detailed diagram of the I/O
structure. See the Detailed Register Descriptions section for
GPO configuration and usage.
