SYNC PROCESSOR (SYNC) (Cont’d)
COUNTER CONTROL REGISTER (CCR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = PSCD
Prescaler Enable bit.
0: Enable the Prescaler by 256
1: Disable the Prescaler and reset it to 7Fh. This
also disables the ICAP2 event.
Bit 6:5 = LCV1, LCV0
VSYNCO Extraction Control
Bit 4:0 = CV4-CV0
Counter Captured Value.
These bits contain the counter captured value in
different modes.
In VSYNCO extraction mode, they contain the
HSYNCI pulse-width measurement.
POLARITY REGISTER (POLR)
Bits 5-4 Read Only, other bits Read/Write
Reset Value: 0000 1000 (08h)
Bit 7 = SOG
Sync On Green Detector
SOG is set by hardware if CSYNCI pulse is not
included in the window between HSYNCI rising
edge and HSYNCI falling edge + dt .
Cleared by software.
Table 19. Sync On Green Window
Bit 6 = Reserved, forced by hardware to 0.
Bit 5 = VPOL
Vertical Sync polarity (read only)
0: Positive polarity
1: Negative polarity
Note: If the Vertical Sync polarity is changing, the VPOL
bit will be updated after a typical delay of 4 msec.
Bit 4 = 2FHDET
Detection of Pre/Post Equalization
pulses (read only).
This bit is continuously updated by hardware. It is
valid when the sync generator and horizontal
analyzer are disabled (HVGEN = 0, HACQ = 0).
0: None detected
1: Pre/Post Equalization pulses detected
Bit 3 = HVSEL
Alternate Sync Input Select.
This bit selects between the two sets of Horizontal
and Vertical Sync inputs
0: HSYNCI2 / VSYNCI2
1: HSYNCI1 / VSYNCI1
Bit 2 = VCORDIS
Extension Disable Signal
(Extension with VGENR Register)
0: enable
1: disable
Bit 1 = CLPINV
Programmable ClampOut pulse

0: Positive
1: Negative
Bit 0 = BLKINV
Programmable blanking polarity
0: Negative
1: Positive
