I
The S1STA register provides status regarding immediate activity and the current state of
operation on the I
the interrupt flag.
Interrupt conditions
If the I
and the SIOE is initialized, then an interrupt is automatically generated when any one of the
following five events occur:
●
●
●
●
●
Selected Slave mode means the device address sent by the Master device at the beginning
of the current data transfer matched the address stored in the S1ADR register.

When the SIOE receives an address that matches the contents of the SFR, S1ADR.
Requirements: SIOE is in Slave Mode, and bit AA = 1 in the SFR S1CON.
When the SIOE receives General Call address. Requirments: SIOE is in Slave Mode,
bit AA = 1 in the SFR S1CON
When a complete data byte has been received or transmitted by the SIOE while in
Master mode. The interrupt will occur even if the Master looses arbitration.
When a complete data byte has been received or transmitted by the SIOE while in
selected Slave mode.
A STOP condition on the bus has been recognized by the SIOE while in selected Slave
mode.
