12.1.4. Ways to Use Digital Output

There are two types of digital output: straight output and ITU-REC output. Each piece of output data is output
at the rising edge of the clock output from the DCK pin (CXD3172AR pin 90). The DCK clock can be reversed
and its delay adjusted through parameter settings (see Table 12.1-3).
Table 12.1-2 summarizes the parameters used for digital output settings.
Parameter
DIFON CAT10_Byte14_bit7
RECOUT CAT10_Byte1_bit0
DIFOUT CAT10_Byte1_bit2
YDSEL CAT1_Byte7_bit4
CDSEL CAT1_Byte7_bit5
S0IN CAT1_Byte7_bit6
S1IN CAT1_Byte7_bit7
S3SEL CAT8_Byte8_bit3-5
BLCKLV CAT10_Byte1_bit3-7
(*1) The settings for the individual parameters are controlled by firmware. For information on how to change
the settings, see 12.6 "Sync Signal Output Setting Method".
Parameter
DCKINV CAT10_Byte14_bit4
DCKDL CAT10_Byte14_bit5-6
DIFCKSEL CAT1_Byte4_bit6-7
* DIFCKSEL is controlled by firmware based on the MODESEL (CAT12_Byte1_bit0-3) setting. Note, however,
that it is only controlled during the initial operation, after which it is open to the user.
