POWER OFF / VDDOK
●
In case of VDDOK falling edge due to under voltage on VCORE or VIO_VMEM
detected, or ‘it_twarn’ bit set to “1” (
Table 18), then multimedia processor is reset
(PORn low during a minimum time of 312.5 µs) and restarted with no time-out. (see
Figure 5). In case of VDDOK falling edge because PWREN balls equals “0”, there is no
reset (PORn still high).
●
In case of PON falling edge (STw4810 switched off from modem) multimedia processor
is also reset with no time-out. We consider that clean switch off between modem and
multimedia processor is done by software directly.

Sleep mode
STw4810 goes into sleep mode by different ways.
Whether VCORE, VIO_VMEM and VAUX are programmed to sleep mode or not is indicated
in
Table 27.
