Table 18. INT_STAT—Register 0x02 (Interrupt Status Register)
Field
Bits
Description
Not Used
[7:4]
N/A
OVR_FLOW_INT1
3
Overflow interrupt status. When set, write 1 to clear.
1: overflow interrupt is detected.
0: overflow interrupt is not detected.
K_LCK_INT2
2
Keylock interrupt status. When set, write 1 to clear.
1: keylock interrupt is detected.
0: keylock interrupt is not detected.
GPI_INT1, 3
1
GPI interrupt status. When set, write 1 to clear.
1: GPI interrupt is detected.
0: GPI interrupt is not detected.
KE_INT1, 3
0
Key events interrupt status. When set, write 1 to clear.
1: key events interrupt is detected.
0: key events interrupt is not detected.
1
The KE_INT, GPI_INT, and OVR_FLOW_INT bits reflect the status of the interrupts when the interrupt types are enabled even if the processor interrupt is masked.
2
The K_LCK_INT bit is the interrupt to the processor when the keypad lock sequence is triggered.
3
If there is a pending key event or GPI interrupt in their respective registers, KE_INT is not cleared until the FIFO is empty, and GPI_INT is not cleared until the cause of
the interrupt is resolved. The host must write a 1 to the KE_INT and GPI_INT bits to clear them.
Table 19. KEY_LCK_EC_STAT—Register 0x03 (Keylock and Event Counter Register)
Field
Bits
Description
K_LCK_EN
[6]
0: lock feature is disabled.
1: lock feature is enabled.
LCK2, LCK1
[5:4]
Keypad lock status[1:0] (00 = unlocked; 11 = locked; read-only bits).
KEC1
[3:0]
Key event count of key event register.
1
The KEC field indicates the key event count of key event registers that have values in the bit (KEC(0000) = 0 events, KEC(0001) = 1 event, KEC(1010) = 10 events). As the
key events are read and cleared, the state machine automatically reduces the event count in KEC.

Data in key event registers is provided as a FIFO, where data is sequentially provided on each read, regardless of an event register read. The user can read the
KEY_EVENTA register only for an event count or can read registers sequentially.
2
KE[6:0] reflects the value 1 to 80 for key press events and the value 97 to 114 for GPI events. For KE[7:0], 0 = key released event, 1 = key pressed event. For GPIEM_CFG,
0 reflects a change in the GPI from GPI_INT_LVL = true to GPI_INT_LVL = false; 1 reflects a change in the GPI in which the GPI_INT_LVL condition becomes true.
