Table 3. CS8402 Switch Definitions - Professional Mode
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.
