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.
