The EM6517-1 has two low power dissipation modes, standby and sleep. Figure 5 is a transition diagram for
these modes.
Operating Modes
3.1 Active Mode
The active mode is the actual CPU running mode. Instructions are read from the internal ROM and executed by
the CPU. Leaving active mode via the halt instruction to go into standby mode, the
Sleep
bit write to go into
Sleep mode or a reset from port A to go into reset mode.
3.2 Standby Mode
Executing a halt instruction puts the
EM6517-1 into standby mode. The voltage
regulator, oscillator, watchdog timer, ADC,
interrupts, SWB, timers and counters are
operating. However, the CPU stops since the
clock related to instruction execution stops.
Registers, RAM and I/O pins retain their
states prior to standby mode. A reset or an
interrupt request if enabled cancels standby.
3.3 Sleep Mode
Writing to the
Sleep
bit in the
RegSysCntl1
register puts the EM6517-1 in sleep mode.
The oscillator stops and most functions of
the EM6517-1 are inactive. To be able to
write to the
Sleep
bit, the
SleepEn
bit in
RegSysCntl2
must first be set to "1". In
sleep mode only the voltage regulator and the reset input are active. The RAM data integrity is maintained.
Sleep mode may be canceled only by a high level of min 10μs at the Reset terminal or by the selected port A
input reset combination, if option
InpResSleep
in register
OPTFSelPB
is turned on.
Due to the cold-start characteristics of the oscillator, waking up from sleep mode may take some time to
guarantee stable oscillation. During sleep mode and the following start up the EM6517-1 is in reset state.
Waking up from sleep clears the
Sleep
flag but not the
SleepEn
bit. Inspecting the
SleepEn
allows to
determine if the EM6517-1 was powered up (
SleepEn
= "0") or woken up from sleep (
SleepEn
= "1").
