Byte Data Link Controller-Digital (BDLC-D)
21.7.4 BDLC State Vector Register
Technical Data
Address:
This register is provided to substantially decrease the CPU overhead
associated with servicing interrupts while under operation of a multiplex
protocol. It provides an index offset that is directly related to the BDLC’s
current state, which can be used with a user-supplied jump table to
rapidly enter an interrupt service routine. This eliminates the need for the
user to maintain a duplicate state machine in software.
