5.3.7 Keyboard Matrix Interrupt Mask Registers (KMIMRA, KMIMR6)
Wake-Up Event Interrupt Mask Register (WUEMR3)
The KMIMR and WUEMR registers enable or disable key-sensing interrupt inputs (KIN15 to
KIN0), and wake-up event interrupt inputs (WUE15 to WUE8). The KMIMRA, KMIMR6, and
WUEMR3 registers can be accessed when the KINWUE bit in SYSCR is set to 1. See section
3.2.2, System Control Register (SYSCR).
