SSIE
Synchronous Serial Interface Enable bit
Clear to disable SSLC.
Set to enable SSLC.
5
STA
Start flag
Set to send a START condition on the bus.
4
ST0
Stop flag
Set to send a STOP condition on the bus.
3
SI
Synchronous Serial Interrupt flag
Set by hardware when a serial interrupt is requested.
Must be cleared by software to acknowledge interrupt.
2
AA
Assert Acknowledge flag
Clear in master and slave receiver modes, to force a not acknowledge (high level
on SDA).
Clear to disable SLA or GCA recognition.
Set to recognise SLA or GCA (if GC set) for entering slave receiver or transmitter
modes.
Set in master and slave receiver modes, to force an acknowledge (low level on
SDA).
This bit has no effect when in master transmitter mode.
