(3)-2. Address Section
The coefficient RAM has a 256-word structure, so the address section is 8 bits. The setup register has a 4-
word structure and the field (address) is specified by the mode section, so the address section data may be
optional.
(3)-3. Data Section
The coefficient RAM and setup register both have a 16-bit structure, so 16 SCK are required.
