Delay timer for SM time service
UMBR-PTR points to the address of the first segment that
no longer belongs to the indication queue.
Settings for individual bits
Base address for access to the internal RAM
Settings for TRDY (ready time valid before sending a reply
frame)
Settings for the number of bits (preamble) in the
synchronous mode.
The following time is set:
TSYN (33-bit asynchronous mode)
TIFG (interframe GAP time; synchronous mode)
Memory lock cell
The BEGIN-PTR points to the lowest segment address of
the indication queue. The BEGIN-PTR must always point to
the beginning of an 8-byte segment.
