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.

Configuration
The insert path AIS bits controls the insertion of Path AIS in the transmit APS stream.
When IPAIS is set high, path AIS is inserted in the outgoing bus. The pointer bytes (H1,
H2, and H3) and the entire synchronous payload envelop (virtual container) is set to all
ones. Normal operation resumes when the IPAIS bit is set low.
The transmit APS stream pointer justification event interrupt enable bit (OPJEE) controls
the activation of the interrupt output when a pointer justification is inserted in the APS
stream. When OPJEE is set high, insertion of pointer justification events in the transmit
APS stream will assert the INTB output. When OPJEE is set low, insertion of pointer
justification events will not affect INTB.
The elastic store error interrupt enable bit (ESEE) controls the assertion of INTB when a
FIFO underflow or overflow has been detected in the elastic store . When ESEE is set high,
FIFO flow error events will assert the INTB output. When ESEE is set low, FIFO flow
error events will not affect INTB.
