Bit Description
7 Analog / Digital Input : Defines usage of the rest if the byte as "analog input" or
digital input". Analog=0, Digital=1 .
If input is described as analog, the following definitions apply to bits 6-0.
6:5 Signal Level Standard (6:5) : Refer to the following bit definitions. Identified by the
level of reference white volts above blank, followed by the level of the sync tips in
volts below
blank.
