FRM_RXCRCSM CEPT CRC-4 Stack Mode. When set to 0, the Sa bits will
be stored based on multiframe alignment. If multiframe
alignment is lost, the stack will not be made available to the
host. When set to 1, the Sa bits will be stored based on an
arbitrary multiframe alignment when only basic frame
alignment can be established.
* See Table 415 for values of L and R.

FRM_RXSA Rx Stack Available. A 1 indicates that the Rx stack is available
for reading. 0 indicates that the stack is being updated and
should not be read. In order to prevent a mix of old and new
data being read, the host should verify that this bit is set to 1
before continuing to read the stack.
* See Table 415 for values of L and R.
