7-4 | TEST PATTERN DDC2 Q-DATA | W | 0h | These bits select the test patten for the Q stream of the DDC2. 0000 = Normal operation using ADC output data 0001 = Outputs all 0s 0010 = Outputs all 1s 0011 = Outputs toggle pattern: output data are an alternating sequence of 10101010101010 and 01010101010101 0100 = Output digital ramp: output data increment by one LSB every clock cycle from code 0 to 65535 0110 = Single pattern: output data are a custom pattern 1 (75h and 76h) 0111 Double pattern: output data alternate between custom pattern 1 and custom pattern 2 1000 = Deskew pattern: output data are AAAAh 1001 = SYNC pattern: output data are FFFFh |
3-0 | TEST PATTERN DDC2 I -DATA | R/W | 0h | These bits select the test patten for the I stream of the DDC2. 0000 = Normal operation using ADC output data 0001 = Outputs all 0s 0010 = Outputs all 1s 0011 = Outputs toggle pattern: output data are an alternating sequence of 10101010101010 and 01010101010101 0100 = Output digital ramp: output data increment by one LSB every clock cycle from code 0 to 65535 0110 = Single pattern: output data are a custom pattern 1 (75h and 76h) 0111 Double pattern: output data alternate between custom pattern 1 and custom pattern 2 1000 = Deskew pattern: output data are AAAAh 1001 = SYNC pattern: output data are FFFFh |
