Section 5 Interrupt Controller
5.2.6
KMIMR is an 8-bit readable/writable register that performs mask control for the keyboard matrix
interrupt inputs (pins KIN7 to KIN0). 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 and 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).

KMIMRA is an 8-bit readable/writable register that performs mask control for the keyboard
matrix interrupt inputs (pins KIN15 to KIN8). To enable key-sense input interrupts from multiple
pin inputs in keyboard matrix scanning/sensing, clear the corresponding mask bits to 0.
KMIMRA is initialized to H'FF by a reset and in hardware standby mode.
