6.23.3 C-DATA BUFFER CONTROL (CAM)
6.23.4 CHANNEL SELECT (CHS)
6.24
The bits in this register can be associated with either channel A or B of the received data. The desired channel is
selected with the CHS bit of the Channel Status Data Buffer Control register.

Receiver Channel Status (address 25h) (Read Only)
Default = 0
0 - One byte mode
1 - Two byte mode
Function:
Sets the C-data buffer control port access mode.
Default = 0
Function:
When set to ‘0’, channel A information is displayed in the receiver channel status register. Channel A
information is output during control port reads when CAM is set to ‘0’ (one byte mode).
When set to ‘1’, channel B information is displayed in the receiver channel status register. Channel B
information is output during control port reads when CAM is set to ‘0’ (one byte mode).
Default = xxxx
Function:
Displays the incoming auxiliary data field width, as indicated by the incoming channel status bits, de-
coded according to IEC60958.
Default = x
Function:
Indicates the channel status block format.
