No valid data, don’t capture and
don’t increment pointer
The leading byte sequence is: FFh-00h-00h.
The MSB of the SAV/EAV code byte is controlled by:
a) Scaler output data: task A
b) VBI data slicer output data: DID[5:0] 5Dh[5:0] = 3Eh
SAV/EAV codes on I port
As a further option, it is possible to provide the scaler with an external gating signal on
pin ITRDY. Thereby making it possible to hold the data output for a certain time and to get
valid output data in bursts of a guaranteed length.
The sketched reference signals and events can be mapped to the I port output pins IDQ,
IGPH, IGPV, IGP0 and IGP1. For flexible use the polarities of all the outputs can be
modified. The default polarity for the qualifier and reference signals is logic 1 (active).
