5.3.7 Keyboard Matrix Interrupt Mask Registers (KMIMRA, KMIMR) and
Wake-Up Event Interrupt Mask Register (WUEMRB)
The KMIMRA, KMIMR, and WUEMRB registers enable or disable key-sensing interrupt inputs
(KIN15 to KIN0), and wake-up event interrupt inputs (WUE7 to WUE0).

Keyboard Matrix Interrupt Mask 7 to 0
These bits enable or disable a key-sensing
input interrupt request (KIN7 to KIN0).
KMIMR6 also performs interrupt request mask
control for pin IRQ6.
