0x1F – Test Control Register (TEST) 
Bit 
Function 
R/W 
Description 
Reset 
7-0 
TEST 
R/W This register is reserved for testing purpose. In normal operation, 
only 0 should be written into this register. 
1 = Analog test mode. Y and C channel portion of the device can 
be tested in this mode. The Y channel ADC output can be obtained 
from HACTIVE, HSYNC and VD[15:8] for bit1, bit0 and bit9-2, 
respectively. The C channel ADC output can be obtained from 
VACTIVE, VSYNC and VD[7:0] for bit1, bit0 and bit9-2, 
respectively.  
2 = Digital test mode1. The sync portion of the device should be 
tested in this mode. The 8-bit input corresponds to TISVN, TEST1, 
TEST2, TDO, TCK, TRST#, TMS, and TDI in the order of bit 7 to 0. 
3 = Analog test mode 1. It is same as the previous analog test 
mode except that the C channel ADC inputs come from TADCP 
and TADCN instead of C_PBIN. 
4 = Digital test mode 2. In addition to digital test mode 1, this test 
mode allows the C channel data to be inputted from VD[7:0]. In this 
mode, only 8-bit output format is allowed. 
5 = Closed Caption test mode. 
6 = Analog test mode 2. The “C channel portion of the device can 
be tested in this mode. The C channel ADC output can be 
obtained from VACTIVE, VSYNC and VD[7:0] for bit1, bit0 and 
bit9-2, respectively. 
7 = Analog DAC output mode. The 6-bit Sync output corresponds 
to TDI, TMS, TRST#, TCK, TISVN and TDO in the order of bit 5 to 
0. Y and Cb/Cr outputs correspond to VD[15:8] and VD[7:0], 
respectively. In this mode, HACTIVE pin will be BGOUT and 
VACTIVE pin will be VSDLY. 
0 
0x20 – Clamping Gain (CLMPG) 
Bit 
Function 
R/W 
Description 
Reset 
7-4 
CLPEND 
R/W These 4 bits set the end time of the clamping pulse in the 
increment of 8 system clocks. The clamping time is determined by 
this together with CLPST. 
A 
3-0 
CLPST 
R/W These 4 bits set the start time of the clamping pulse in the 
increment of 8 system clocks. It is referenced to PCLAMP position.
