Real-Time Clock in Power Saving Modes
Once started in the normal mode, the oscillator as well as the whole real-time clock could remain in
operation during certain power-down modes where the power supply could be reduced to a
minimum of
3 V
. These are the power down modes 2 and 3, where other functional units of the
C505L are powered down (
See “Power Saving Modes” on Page 50.
).
The upper 40-bit content of the real-time clock counter can be compared with the content of the
programmable RTINT register in order to generate an interrupt request while the C505L is in one of
software power-down modes 2 or 3, provided all of the following conditions are fulfilled:
– The C505L is in one of the software power-down modes 2 or 3,
– Wake-up from software power-down is enabled (bit EWPD = 1 in SFR PCON1)
– Real-time clock wake-up source is selected (bit WS = 1 in SFR PCON1),
– The real-time clock interrupt is enabled (bit ERTC = 1 of RTCON), and
– Normally operating
V
DD
levels are maintained
In this case, the handling is similar to the wake-up from power-down through P3.2/INT0.
