I2C additional function register
(1) bit 0: Time-out mode bit (TOM)
Setting the time-out mode bit “1” , continuity of I2C-Bus busy
state for about 125 ms (XIN = 8 MHz) makes time-out flag “1”
and time-out interrupt. Restart condition resets the time-out
timer.
(2) bit 1: Time-out flag (TOF)
Time-out flag becomes “1” when the time-out state occurs.
Writing “1” to this bit, time-out timer is reset, and this bit is
cleared “0” also.
(3) bit 2: SM-Bus interface pin input threshold select bit (TIS2)
The SM-Bus interface pin input threshold is selected by this bit.
Setting this bit “0”, the SM-Bus interface pin input threshold is
for SM-Bus Ver1.0 specification, and setting this bit “1”, it is for
SM-Bus Ver1.1 specification.
(4) Stop condition flag (SCF)
This flag turns to “1”, when the stop condition is generated or
detected. This bit is cleared “0” at reset, or when I2C-Bus inter-
face enable bit is “0” or writing this bit “1”. This bit is available
when I2C-Bus interface enable bit is “1”.

I2C additional function register
Time-out mode bit (TOM)
0 : disable
1 : enable
Time-out flag (TOF)
0 : Not generated
1 : Generated
*Writing this bit “1”, this flag is cleared to “0”.
SM-Bus interface pin input threshold select bit (TIS2)
0 : Ver1.0 (VIL=0.6V,VIH=1.4V)
1 : Ver1.1 (VIL=0.8V,VIH=2.1V)
Stop condition flag (SCF)
0 : Not detect stop condition
1 : Detect stop condition
*Writing this bit “1”, this flag is cleared to “0”.
Not used (returns “0” when read)
(S3 : address 003116)
