Semi-Standby
MPIF's should be initialized according the FMS information.
MPIF should deliver 4 observers:
POR= 0; normal operation
MSUP = 1: Main supply is present
ASUP = 1; audio supply is present
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 according FMS
information
All observers present with correct state? appropriate Observer errorNo
Yes
Initialize video processing IC's according FMS information:
- Spider
Initialize source selection according FMS
and CHS information
initialize Columbus by triggering CHS Columbus Init interface
initialize 3D Combfilter by triggering CHS 3D Comb filter Init interface
initialize AutoTV by triggering CHS AutoTV Init interface
See appropriate CHS documents for further details.
