12.1.1 Sa Bit Change of State
The DS26504 can provide an interrupt whenever one of the multiframe based Sa bit patterns changes.
Using the SR5 and IMR5 registers, the user can enable interrupts on a change of state for Sa4, Sa5, Sa6,
Sa7 and Sa8 multiframe bit patterns. This function is useful for monitoring the Sa6-based SSM message.
