Valid for
Forced re-addressing. If
dev
re-addressing is disabled
non zero = Forced re-addressing is enabled.
Enable/Disable Automatic Serial Polling. If
bd
then Automatic Serial Polling is disabled. Otherwise, it
is enabled.
CIC Protocol. If value is 0, then CIC Protocol is not
bd
used. Otherwise, CIC Protocol is used.
Enable/Disable Hardware Interrupts. If

Assert/Unassert REN. If
bd
unasserted. Otherwise, the REN line is asserted.
/
EOS termination mode and character. The value lower
bd
dev
byte determines the EOS character. The value upper
byte third bit determines whether reads are terminated
when the EOS character is detected. The value upper
byte fourth bit determines whether EOI is set with the
EOS character on writes. The value upper byte fifth bit
determines whether all 8 bits of the EOS character
should be compared; otherwise, only 7 bits are
compared.
/
Recognize EOS. If
bd
dev
terminated when the End-Of-String (EOS) character is
detected. Otherwise, EOS detection is disabled.
/
Assert EOI. If
bd
dev
when the EOS character is sent. Otherwise, EOI is not
asserted.
