MIPS reads the wake up reason
from standby µP.
Semi-Standby
MPIF's should be initialized according the FMS information.
MPIF should deliver 2 observers:
POR= 0; normal operation
ROK = 1; reference frequency is present (coming from AVIP)
(AVIP's need to be started before the MPIF's in order to have a good clock distribution).
AVIP default power-up mode is Standby. The Viper instructs AVIP via I²C to enable all the
PLL's and clocks and hence enter to Full Power mode. See FMS AVIP for further details
and the rest of the initialization.
Initialize tuners and Hirate
All observers present with correct state?

Disable all supply related protections and
switch off the +2V5, +3V3 DC/DC converter.
switch off the remaining DC/DC

Switch the NVM reset
line HIGH.
Wait for the +8V6 to be detected if not yet present. (if
it does not come, the standby µP will enter a
protection mode, this is not a dead end here)
Do not enter semi-standby state in case of an LPL
scanning backlight LCD set before 4s preheating timer has
elapsed.

Initialize Ambilight with Lights off.
- Register PIIConfig of the Pacific3: LVDS function should be set to 0
(CMOS input) in the Baby Jaguar platform.
- POIConfig: lvds function should be set to 0 (CMOS out on Baby)
- PanelConfig register: PanelOff = 0, PanelOn = 1. P3 can always be
on, switching of lvds is done through PNX.
