These STAL blocks perform the pointer processing required for the transmit APS interface for
each channel. The other STAL blocks are slaved to these STAL blocks.

The diagnose loss of pointer control bit (DLOP) allows downstream pointer processing
elements to be diagnosed. When DLOP is set high, the new data flag (NDF) field of the
payload pointer inserted in the APS stream inverted causing downstream pointer processing
elements to enter a loss of pointer (LOP) state.
The transmit APS stream negative pointer justification interrupt status bit (NPJI) is set high
when the STAL inserts a negative pointer justification event on the APS stream.
The transmit APS stream positive pointer justification interrupt status bit (PPJI) is set high
when the STAL inserts a positive pointer justification event on the APS stream.
The elastic store error interrupt status bit (ESEI) is set high when STAL detects a FIFO
underflow or overflow event.
