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 ,549.
0: Enables a key-sensing input interrupt request
1: Disables a key-sensing input interrupt
request

Description
Wake-Up Event Interrupt Mask 7 to 0
These bits enable or disable a wake-up event
input interrupt request (WUE7 to WUE0).
0: Enables a wake-up event input interrupt
request
1: Disables a wake-up event input interrupt
request
Figure 5.2 shows the relationship between interrupts IRQ7 and IRQ6, interrupts KIN15 to KIN0,
interrupts WUE7 to WUE0, and registers KMIMRA, KMIMR, and WUEMRB.
