6.8 Output Mode
M65863FP
Dolby Digital Decoder
Output channel mode is controlled by the control register.
One of Dual Mono,1/0,2/0,2/1,2/2,3/0,3/1,3/2 modes can be selected. The number of output channels
depends on the encoded data. Maximum channels are limited by the encoded data except for 1/0 encoded
data and Pro Logic encoded data.
In the case of 1/0 encoded data, 2/0 (monaural stereo) output mode can be selected. Pro Logic encoded
data is the same as the 3/1 mode. If a high number of channels beyond the input data channels is specified
for output in the output mode, the over-channels output data is '0'.
One of 4 output modes can be selected when the main audio services the Dual Mode.
