Keyboard Control Register Access Enable
Enables or disables CPU access for input control
registers (KMIMRA, KMIMR6, WUEMR3) of KINn and
WUEn pins, input pull-up MOS control register
(KMPCR6) of the KINn pin, registers (TCR_X/TCR_Y,
TCSR_X/TCSR_Y, TICRR/TCORA_Y,
TICRF/TCORB_Y, TCNT_X/TCNT_Y, TCORC/TISR,
TCORA_X, TCORB_X) of 8-bit timers (TMR_X,
