Multichannel Frame Delay

The 4-bit
MFD
sync pulse and the first data bit in multichannel mode. The value of
the number of serial clock cycles of the delay. Multichannel frame delay
allows the processor to work with different types of interface devices.
A value of 0 for
data bit. The maximum value allowed for
occur before data from the last frame has been received, because blocks of
data occur back-to-back.

Window Size

The window size (
enabled/disabled by the multichannel select registers. This range of words
is called the active window. The number of channels can be any value in
the range of 0 to 15, corresponding to active window size of 8 to 128, in
increments of 8; the default value of 0 corresponds to a minimum active
