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) and IRQ6 pin. 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).
Note:
Figure 5.2 shows the relationship between interrupts IRQ6, interrupts KIN7 to KIN0, and registers
KMIMR.
