Keyboard Matrix Interrupt Mask Register (KMIMR)
KMIMR is provided as a register for keyboard matrix interrupt masking. This register controls
interrupts from the KEYIN
Bits KMIMR7 to KMIMR0 of KMIMR correspond to key sense inputs KEYIN
In interrupt mask bit initialization, bit KMIMR6 corresponding to the IRQ
enable interrupt requests, while the other mask bits are set to disable interrupts.
KMIMR is an 8-bit readable/writable register used in keyboard matrix scan/sense. This register
initializes to a state in which only the input at the IRQ
interrupts from two or more pins in keyboard matrix scanning and sensing, clear the corresponding
mask bits to 0.
Figure 4.3 shows the relationship between the IRQ
Bits 7 to 0—Keyboard Matrix Interrupt Mask (KMIMR7 to KMIMR0): These bits control
