ENS1
Clock rate bit 2, see Table 48.
Enable serial I/O
. ENS1 = 0: serial I/O disabled and reset. SDA and SCL outputs are high-Z.
ENS1 = 1: serial I/O enabled.
START flag.
When this bit is set in slave mode, the hardware checks the I
2
C-bus and generates
a START condition if the bus is free or after the bus becomes free. If the device operates in
master mode it will generate a repeated START condition.
STOP flag
. If this bit is set in a master mode a STOP condition is generated. A STOP condition
detected on the I
2
C-bus clears this bit. This bit may also be set in slave mode in order to recover
from an error condition. In this case no STOP condition is generated to the I
2
C-bus, but the hard
ware releases the SDA and SCL lines and switches to the not selected receiver mode. The
STOP flag is cleared by the hardware.
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 GC (bit S1ADR.0) and AA = 1.
A data byte has been received or transmitted in master mode (even if arbitration 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; GC (bit S1ADR.0) = 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 a 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.
Clock rate bits 1 and 0; see Table 48.
