This register indicates the last received SaX bit. This can be used in conjunction with the
RLS7 register to
determine which SaX bits have changed. The user can program which Sa bit positions should be monitored via the
E1RSAIMR register, and when a change is detected through an interrupt in RLS7.0, the user can determine which
bit has changed by reading this register and comparing it with previous known values.
Bit 4: Last Received Sa4 Bit (Sa4)
Bit 3: Last Received Sa5 Bit (Sa4)
Bit 2: Last Received Sa6 Bit (Sa5)
Bit 1: Last Received Sa7 Bit (Sa7)
Bit 0: Last Received Sa8 Bit (Sa8)
