IDLE MODE
The user’s software can invoke the Idle Mode When
the microcontroller is in this mode power consump-
tion is reduced The Special Function Registers and
the onboard RAM retain their values during idle pe-
ripherals continue to operate but the processor
stops executing instructions Idle Mode will be exited
if the chip is reset or if an enabled interrupt occurs
The PCA timercounter can optionally be left run-
ning or paused during Idle Mode The Watchdog
Timer continues to count in Idle Mode and must be
serviced to prevent a device RESET while in Idle
POWER DOWN MODE
To save even more power a Power Down mode can
be invoked by software In this mode the oscillator
is stopped and the instruction that invoked Power
Down is the last instruction executed The on-chip
RAM and Special Function Registers retain their val-
ues until the Power Down mode is terminated
On the 8XC51GB either a hardware reset or an ex-
ternal interrupt can cause an exit from Power Down
Reset redefines all the SFRs but does not change
the on-chip RAM An external interrupt does not re-
define the SFR’s or change the on-chip RAM An
external interrupt will modify the interrupt associated
SFR’s in the same way an interrupt will in all other
modes The interrupt must be enabled and config-
ured as level sensitive To properly terminate Power
Down the reset or external interrupt should not be
executed before VCC is restored to its normal oper-
ating level The reset or external interrupt must be
held active long enough for the oscillator to restart
and stabilize The Oscillator Fail Detect must be dis-
abled prior to entering Power Down
DESIGN CONSIDERATIONS
 When the idle mode is terminated by a hardware
reset the device normally resumes program exe-
cution from where it left off up to two machine
cycles before the internal reset algorithm takes
control On-chip hardware inhibits access to inter-
nal RAM in this event but access to the port pins
is not inhibited To eliminate the possibility of an
unexpected write when Idle is terminated by re-
set the instruction following the one that invokes
Idle should not be one that writes to a port pin or
to external memory
 As RESET rises the 8XC51GB will remain in re-
set for up to 5 machine cycles (60 oscillator peri-
ods) after RESET reaches VIH1
