Table 20. INT_STAT—Register 0x02 (Interrupt Status Register)

Field

Bit

Description

CMP2_INT

5

Comparator interrupt status. When set, write 1 to clear.

1: Comparator 2 interrupt is detected.

0: Comparator 2 interrupt is not detected.

CMP1_INT

4

Comparator interrupt status. When set, write 1 to clear.

1: Comparator 1 interrupt is detected.

0: Comparator 1 interrupt is not detected.

3

Overflow interrupt status. When set, write 1 to clear.

1: Overflow interrupt is detected.

0: Overflow interrupt is not detected.

2

Keylock interrupt status. When set, write 1 to clear.

1: Keylock interrupt is detected.

0: Keylock interrupt is not detected.

1

GPI interrupt status. When set, write 1 to clear.

1: GPI interrupt is detected.

0: GPI interrupt is not detected.

0

Key events interrupt status. When set, write 1 to clear.

1: Key events interrupt is detected.

0: Key events interrupt is not detected.

cause of the interrupt is resolved. The host must write a 1 to the INT bits to clear.

Table 21. KEY_LCK_EC_STAT—Register 0x03 (Keylock and Event Counter Register)

Field

Bit

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).

[3:0]

Key event count of key event register.

key events are read and cleared, the state machine automatically reduces the event count on KEC.
