Preliminary Data Sheet

21 28-Channel Framer Block Functional Description
21.22.6 Receive Data Link Stack Idle Modes
No data link stack features for the following frame formats:
21.22.7 Receive Data Link Stack Pointer
The stack pointer maintains two pointers: an internal pointer and a host pointer. The pointer identifies which stack
is active for the host and which stack is active for the internal logic. These pointers will always point to opposite
stacks. When the TDM interface block is writing Sa bits or D bits to the stack, then the internal pointer may be
selecting the upper stack. In this case, the host pointer is selecting the lower stack for the host reads. At the begin-
ning of each double multiframe or each superframe, a pointer switch takes place. This switch takes place during the
time in which the host is prevented from accessing the stack for a particular link.
A stack pointer is maintained for each of the links individually.
