SYNC PROCESSOR (SYNC) (Cont’d)
4.4.10 Register Description
CONFIGURATION REGISTER (CFGR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = HACQ Horizontal Sync Analyzer Mode
Set by software, reset by hardware when the
measurement is done. The sync generator must
be disabled (HVGEN=0).
0 : Measurement is done, the result can be read
in HGENR.
1: Start measuring HSYNCO/HFBACK low lev-
el.
Bit 6 = VACQ Vertical Sync Analyzer Mode
Set by software, reset by hardware when the
measurement is done. The sync generator must
be disabled (HVGEN=0).
0: Measurement is done, and the result can be
read in VGENR.
1: Start measuring the number of scan lines dur-
ing VSYNCO/VFBACK low level.
Bit 5 = Reserved. Must be cleared.
Bit 4 = 2FHINH Inhibition of Pre/Post equalization
pulses.
This
function
removes
pre/post
equalization
pulses on HSYNCO signal. The sync generator
and the Horizontal sync analyzer must both be
disabled (HVGEN=HACQ=0).
0: Disable
1: Enable
Bit 3 = VEXT VSYNCO pulse width extension in
case of post-equalization pulses.
The sync generator and the Horizontal and
Vertical sync analyzer must be disabled (HVGEN
= 0, HACQ = 0, VACQ = 0, VCORDIS=0). Vertical
extension must be enabled (VGENR > 0
).
0: Disable
1: Enable
Bits 2:0 = Q’2..Q’0
These are the read/write LSB of the VGENR 11-bit
counter. Refer to Figure 44.
