When the keypad lock interrupt mask timer is enabled, the user must press two specific keys before a keylock interrupt is generated or keypad events are recorded.
After the keypad is locked, the first time that the user presses any key, a key event interrupt is generated. No additional interrupt is generated unless both unlock key
sequences are correct; then a keylock interrupt is generated. When the interrupt mask timer is disabled (0), an interrupt is generated only when the correct full unlock
sequence is completed.

The Unlock 1 timer and Unlock 2 timer keys can be either a key sequence or GPIEM_CFG sequence. The unlock timer keys can be programmed with any value of the
keys in the keypad matrix or any GPI values that are part of the key event table. The keylock enable bit (Bit 6, Register 0x03) must be set to lock the keypad.
