Idle mode bit: 0 = normal operation, 1 = Idle mode operation
Power-down bit: 0 = normal operation, 1 = Power-down mode

Watchdog load enable: 0 = loading of Watchdog timer disabled,
1 = loading of Watchdog timer enabled
enable Watchdog: 0 = Watchdog disabled, 1 = Watchdog enabled;
once this bit is set only a synchronous reset can clear it
radio frequency interference bit: disables toggling of internal ALE
signal during on-chip program access if set to logic 1
auxiliary RAM disable: setting this bit will force MOVX instructions
to access off-chip memory instead of AUXRAM
