KMIMR is an 8-bit readable/writable register that performs mask control for the keyboard matrix
interrupt inputs (pins
KIN7 to KIN0) and pin IRQ6. To enable key-sense input interrupts from
multiple pin inputs in keyboard matrix scanning/sensing, clear the corresponding mask bits to 0.
KMIMR is initialized to H'BF by a reset or in hardware standby mode and only
IRQ6 (KIN6)
input is enabled.
Bits 7 to 0—Keyboard Matrix Interrupt Mask (KMIMR7 to KMIMR0): These bits control
key-sense input interrupt requests (KIN7 to KIN0).

Description
0
Key-sense input interrupt requests enabled
1
Key-sense input interrupt requests disabled
(Initial value)*
Note:
*
However, the initial value of KMIMR6 is 0, as KMIMR6 bit masks the
IRQ6 interrupt
request and enables key-sense input.
