Reserved
The value read from these bits is indeterminate. Do not set these bits.
Power-Off Flag
Cleared to recognize next reset type.
Set by hardware when VCC rises from 0 to its nominal voltage. Can also be set
by 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.
If IDL and PD are both set, PD takes precedence.
