Description
Keyboard Matrix Interrupt Mask 15 to 8
These bits enable or disable a key-sensing
input interrupt request (KIN15 to KIN8).
0: Enables a key-sensing input interrupt request
1: Disables a key-sensing input interrupt
Description
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.
0: Enables a key-sensing input interrupt request
1: Disables a key-sensing input interrupt
