RS170 Default Register Values
The tables below show the values programmed for the
RS170 Format (using a 14.31818 MHz clock signal) and
how they compare against the actual EIA RS170 Specifica-
tions. The default signals that will be output are CSYNC,
CBLANK, HDRIVE and VDRIVE. The device initially starts
at the beginning of the odd field of interlace. All signals
have active low pulses and the clock is disabled at power
up. Registers 13 and 14 are not involved in the actual sig-
nal information. If the Vertical Interrupt was selected so that
a pulse indicating the active lines would be output.
