Table 182 Pulse B trigger position for Task B (SA F8, SA F9)
PULSE Generator Register Set for Start of line for
scaler Register Set B (F8h ... F9h)
Pulse B trigger position for Task B data relative to the
pule generator counter measured in clock cycles.
lowest value of pulse B
...
Recommended value for ITU style receiver operating with
SAV codes aligned
Recommended value for ITU style receiver operating with
EAV codes aligned
...
latest position of pulse B
Note:
If PGHBPS is greater than PGLEN * 4 then the pulse B will
not be generated!
