Exiting Standby mode
After the system has entered the Standby 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
there 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 Standby mode
When Standby 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.
