14.2
When the CMM bit (bit 0) in the connection memory low is zero, the per-channel transmission is set to the normal
channel-switching. The connection memory low bit assignment for the channel transmission mode is shown in
Table 12 on page 35.

In normal functional mode, these bits MUST be set to zero.
Variable/Constant Delay Control
When this bit is low, the output data for this channel will be taken from con-
stant delay memory.
When this bit is set to high, the output data for this channel will be taken from
variable delay memory. Note that VAREN must be set in Control Register
first.
Reserved. In normal functional mode, this bit MUST be set to zero.
Source Stream Address
The binary value of these 4 bits represents the input stream number.
Source Channel Address
The binary value of these 8 bits represents the input channel number.
Connection Memory Mode = 0
If this is low, the connection memory is in the normal switching mode. Bit 13 -
1 are the source stream number and channel number.
