Data in key events is provided as a FIFO, where data is sequentially provided on each read, regardless of an event register read. The user can read register Event A 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.

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.
2
The Unlock 1 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.
