Gain setting control is set by inputting 8-bit data fo the 1st word first and inputting 8-bit data of the 2nd

code of the 2nd word is input after the input of the 1st word, the contents of the 1st word are ignored.

(i)

When gain setting control is valid

Remark Because A/

µ-law, power down control is input after input of gain setting control (1st word),

gain setting control (1st word) becomes invalid and gain setting control (2nd word) also

becomes invalid.

(iii) When gain setting control is invalid –2

Remark Because gain setting control (2nd word) is input before gain setting control (1st word), gain

setting control (1st word) becomes invalid. Then, because A/

µ-law, power down control

is input even if gain setting control (1st word) is input, gain setting control (1st word)

becomes invalid.

(ii) When gain setting control is invalid –1
