Exiting stand-by mode
After the system has entered the Stand-by Mode, the procedure to exit this mode consists of
a standard Power-on sequence, with the only difference that the RAM is already powered
through V
It is recommended to held the device under RESET (RSTIN pin forced low) until external
V
device is maintained under reset by the internal low voltage detector circuit (implemented
inside the main voltage regulator) till the internal V
is no warranty that the device stays under reset status if RSTIN is at high level during
power ramp up. So, it is important the external hardware is able to guarantee a stable
ground level on RSTIN along the power-on phase, without any temporary glitch.
The external hardware shall be responsible to drive low the RSTIN pin until the V
stable, even though the internal LVD is active.
Once the internal Reset signal goes low, the RAM (still frozen) power supply is switched to
the main V
At this time, everything becomes stable, and the execution of the initialization routines can
start: XRAM2EN bit can be set, enabling the RAM.
Real-time clock and stand-by mode
When Stand-by mode is entered (turning off the main supply V
counting can be maintained running in case the on-chip 32 kHz oscillator is used to provide
the reference to the counter. This is not possible if the main oscillator is used as reference
for the counter: Being the main oscillator powered by V
oscillator is stopped.
