The register settings in Table 41 are used to generate an SD NTSC
CVBS output on DAC A, S-video on DACs B and C, and YPrPb
on DACs D, E, and F. Upon power-up, the subcarrier registers
are programmed with the appropriate values for NTSC. All
other registers are set as normal/default.

For PAL CVBS output on DAC A, the same settings are used,
except Subaddress 0x40 is programmed to 0x11 and the F
registers are programmed as shown in Table 42.
