Default
0x0
One shot trigger for external trigger B signal when written with '1'
Default
0x0
Controls which timing counter is forced
0 = force counter now mode is disabled
1 = force H count now to H_TOTAL only
2 = force H count to H_TOTAL and V count to V_TOTAL in progres-
sive mode and V_TOTAL-1 in interlaced mode
3 = reserved
0x0
Selects the trigger signal as force count now trigger
0 = selects CRTC_TRIG_A and CRTC_TRIG_A_POL
1 = selects CRTC_TRIG_B and CRTC_TRIG_B_POL
0x0
Reports the status of force count now, a sticky bit.
0 = CRTC force count now has not occurred
1 = CRTC force count now has occurred
0x0
Resets D2CRTC_FORCE_COUNT_NOW_OCCURRED when writ-
ten with '1'
Default
0x0
Selects the signal used for flow control in CRTC2
0 = logic 0
1 = GENERICA pin
2 = GENERICB pin
3 = HPD1 pin
4 = HPD2 pin
5 = DDC1DATA pin
6 = DDC1CLK pin
7 = DDC2DATA pin
8 = DDC2CLK pin
9 = DVOCLK(1) pin
10 = VHAD(0] pin
11 = VHAD[1] pin
12 = VPHCTL pin
13 = VIPCLK pin
14 = DVALID pin
15 = PSYNC pin
0x0
Reports the status of force count now, a sticky bit.
0 = CRTC force count now has not occurred
1 = CRTC force count now has occurred
0x0
Controls at which pixel position flow control can start to happen
0 = flow control only start to happen on odd-even pixel boundary
1 = flow control can start at any pixel position
0x0
Reports the value of the flow control input signal
0 = output of source mux of flow control signal is low
1 = output of source mux of flow control signal is high
Default
