is programmed as high, a high on that pin is considered active
and meets the interrupt requirement. If the interrupt is pro-

meets the interrupt requirement.

GPI data and interrupt status are reflected in the GPIO interrupt
and data status registers (Register 0x11 through Register 0x16).
Caution must be taken during software implementation because
an interrupt may be set immediately after register settings. To
prevent this, correct logic levels must be present at the GPIs,
and the GPIO interrupt level must be set before GPIO interrupt
enable or GPI event FIFO enable registers are set. Figure 8 shows
the interrupt generation scheme, where Dx represents any one
of the 18 GPIOs.

For a GPI that is set as active high, and is enabled in the key
event table, the state machine adds an event to the event count
and event table whenever that GPI goes high. If the GPI is set to
active low, a transition from high to low is considered a press
and is also added to the event count and event table. After the
interrupt state is met, the state machine internally sets an
interrupt for the opposite state programmed in the register to
prevent polling for the released state, thereby saving current.
After the released state is achieved, it is added to the event table.
The press and release are still indicated by Bit 7 in the event
register (Register 0x04 through Register 0x0D). The GPI events
can also be used as unlocked sequences.

When the GPI_EM_REGx bit in Register 0x20 through Register
0x22 is set, GPI events are not tracked when the keypad is
locked. The GPIEM_CFG bit (Register 0x01, Bit 6) must be
cleared for the GPI events to be tracked in the event counter
and event table when the keypad is locked.
Figure 8. GPIO Interrupt Generation
GPI Events
A column or row configured as a GPI can be programmed to be
part of the key event table and therefore also capable of gener-
ating a key event interrupt. A key event interrupt caused by a
GPI follows the same process flow as a key event interrupt
caused by a key press. GPIs configured as part of the key event
table allow single key switches and other GPI interrupts to be
monitored. As part of the event table, GPIs are represented by
the decimal value 97 (0x61 or 1100001) through the decimal
value 114 (0x72 or 1110010). See Table 13 and Table 14 for GPI
event number assignments for rows and columns.
50 Microsecond Interrupt Configuration
The ADP5588 gives the user the flexibility of deasserting the
interrupt for 50 μs while there is a pending event. When the
INT_CFG bit in Register 0x01 is set, any attempt to clear the
interrupt bit while the interrupt pin is already asserted results in
a 50 μs deassertion. When the INT_CFG bit is cleared, processor
interrupt remains asserted if the host tries to clear the interrupt.
This feature is particularly useful for software development and
edge triggering applications.
