and consumer modes; however, the CS8402 out-

put to the transformer must be modified, as

shown below Table 4, to be compatible with the

consumer interface. Table 4 lists the switch set-

tings for consumer mode. If the C input of

connector P3 is used, the input bits are logically

OR’ed with the appropriate DIP switch bits. In

Tables 3 and 4, the ’C’ bits listed in the com-

ment section are taken from the Digital Audio

Interface specifications. As an example, switch 6

in the professional mode (Table 3) controls C9

which is the inverse of channel status bit 9 (also

listed as byte 1, bit 1 in the CS8402 data sheet).

Channel status bit 9 is one of four bits indicating

channel mode. Therefore, using DIP switch 6,

only two of the available channel modes may be

selected. The C input port on connector P3 may

be used to select other channel modes. See the

CS8401 & CS8402 part data sheet for more in-

formation on the operation of the CS8402.
