Bits 7 to 0—Keyboard Matrix Interrupt Mask (KMIMR15 to KMIMR8): These bits control
key-sense input interrupt requests (KIN15 to KIN8).
Bits 7 to 0
KMIMR15
to KMIMR8 Description
0 Key-sense input interrupt requests enabled
1 Key-sense input interrupt requests disabled (Initial value)
Figure 5.2 shows the relationship between interrupts IRQ7 and IRQ6, interrupts KIN15 to KIN0,
and registers KMIMR and KMIMRA.
