Normal mode or Green mode to Sleep mode:
Step 1: Clear MODE0 to 0
Step 2: Execute the HALT instruction
After Step 2, the operation mode is changed to Sleep
mode, the PLLEN and MODE1 are cleared to 0 by
hardware.
Normal mode or Green mode to Idle mode:
Step 1: Set MODE0 to 1
Step 2: Execute the HALT instruction
After Step 2, the operation mode is changed to Idle
mode, the PLLEN and MODE1 are cleared to 0 by
hardware.
Green mode to Normal mode:
Step 1: Set PLLEN to 1
Step 2*: Software delay 2ms at least
Step 3: Set MODE1 to 1
After Step 3, operation mode is changed to Normal
mode.
Note: * Must delay 20ms at least, if you want to use
stable clock source
Sleep mode or Idle mode to Green mode:
Method 1: Any reset condition occurred
Method 2: Any interrupt is active
Method 3: A falling edge on any pin of Port A
After any source of the above descriptions, operation
mode is changed to Green mode.
The reset conditions include power on reset, external
reset, WDT time-out reset. By examining the processor
status flags, PDF and TO, the program can distinguish
between different reset conditions . Refer to the Reset
function for detailed description.
Afalling edge on port Aand interrupt can be considered
as a continuation of normal execution. Each bit in port A
can be independently selected to wake-up the device by
mask option. Awakening from Port A stimulus, the pro-
gram will resume execution of the next instruction.
The interrupts from the Sleep mode or Idle mode may
cause two sequences to occur in the controller. One is if
the related interrupt is disabled or the interrupt is en-
abled but the stack is full, the program will resume exe-
cution at the next instruction. The other is if the interrupt
is enabled and the stack is not full, the regular interrupt
response takes place. It is necessary to mention that if
an interrupt request flag is set to 1 before entering the
Sleep mode or Idle mode, the wake-up function of the
related interrupt will be disabled.
Once Idle mode wake-up event occurs, it will take 1024
system clock period or SST delay time to resume to
Green mode. In this case, a dummy period is inserted
after a wake-up. If the wake-up results from an interrupt
acknowledge signal, the actual interrupt subroutine exe-
cution will be delayed by one or more cycles. If the
wake-up results in the next instruction execution, this
will be executed immediately after the dummy period is
completed.
To minimize power consumption, all the I/O pins should
be carefully managed before entering the Sleep mode
or Idle mode.
The Sleep mode or Idle mode is initialized by the
HALT instruction and results in the following.
The system clock will be turned off
The WDT function will be disabled if the WDT clock
source is the instruction clock
The WDT function will be disabled if the WDT clock
source is the 32768Hz in Idle mode
The WDT will still function if the WDT clock source is
the WDT OSC
If the WDT function is still enabled, the WDT counter
and WDT prescaler will be cleared and recounted
again
The contents of the on chip RAM and registers remain
unchanged
All the I/O ports maintain their original status
The PDF flag is set and the TO flag is cleared by hard-
ware.
