Description
NMI Edge Select
Selects the valid edge of the NMI interrupt input.
0: An interrupt is requested at the falling edge of NMI
1: An interrupt is requested at the rising edge of NMI
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,
TMR_Y), and timer connection registers (TCONRI,
TCONRO, TCONRS, SEDGR).
0: Enables CPU access for registers of TMR_X and
1: Enables CPU access for input control registers of
RAM Enable
Enables or disables on-chip RAM. The RAME bit is
initialized when the reset state is released.
0: On-chip RAM is disabled
1: On-chip RAM is enabled
