software.
General-purpose flag 1
One use is to indicate whether an interrupt occurred during normal operation or
during Idle mode.
General-purpose flag 0
One use is to indicate whether an interrupt occurred during normal operation or
during Idle mode.
Power-down Mode bit
Cleared by hardware when an interrupt or reset occurs.
Set to activate the Power-down mode.
If IDL and PD are both set, PD takes precedence.
Idle Mode bit
Cleared by hardware when an interrupt or reset occurs.
Set to activate the Idle mode.
