C-bus data transfer to subaddresses
The following tables describe the data transfer to or from the subaddresses 0 to 7. See Sections 7.9.3.2, 7.9.3.3
and 7.9.3.4 for information of the data transfer modes.

Data transfer to subaddresses
7.9.4.3
Quantization matrix SRAM
SRAM memory containing a constant table for the macroblock processor quantization function.
The data to be loaded into this memory will be part of the application software and described in the software specification.
Remark
: Data may only be sent to this subaddress if the SAA6750H is in the init mode (see Table 23).
7.9.4.4
Microcode SRAM
SRAM memory containing the ASIP’s microcode.
The microcode to be loaded into this memory will be part of the application software and described in the software
specification.
Remark
: Data may only be sent to this subaddress if the SAA6750H is in the init mode (see Table 23).
