Enhanced TV microcontrollers with
On-Screen Display (OSD)
SAA567x; SAA569x
SI
Serial Interrupt flag:
This flag is set and an interrupt request is generated, after
any of the following events occur:
A START condition is generated in master mode
The own slave address has been received during AA = 1
The general call address has been received while S1ADR.GC and AA = 1
Adatabytehasbeenreceivedortransmittedinmastermode(evenifarbitration
is lost)
A data byte has been received or transmitted as selected slave
A STOP or START condition is received as selected slave receiver or
transmitter. While the SI flag is set, SCL remains LOW and the serial transfer
is suspended. SI must be reset by software.
Assert Acknowledge flag:
When this bit is set, an acknowledge is returned
after any one of the following conditions:
Own slave address is received
General call address is received (S1ADR.GC = 1)
A data byte is received, while the device is programmed to be a master receiver
A data byte is received, while the device is selected slave receiver.
When the bit is reset, no acknowledge is returned. Consequently, no interrupt is
requested when the own address or general call address is received.
