5.2.5
STOP BIT
The Stop bit (see Figure 5-6) Indicates the end of the
I2C Data Transfer Sequence. The Stop bit is defined as
the SDA signal rising when the SCL signal is “High”.
A Stop bit resets the I2C interface of the other devices.

Transmit Mode.
5.2.6
CLOCK STRETCHING
“Clock Stretching” is something that the Secondary
Device can do, to allow additional time to “respond” to
the “data” that has been received.
The MCP40D17/18/19 will not strech the clock signal
(SCL) since memory read accesses occur fast enough.
5.2.7
ABORTING A TRANSMISSION
If any part of the I2C transmission does not meet the
command format, it is aborted. This can be intentionally
accomplished with a START or STOP condition. This is
done so that noisy transmissions (usually an extra
START or STOP condition) are aborted before they
corrupt the device.
5.2.8
IGNORING AN I2C TRANSMISSION
AND “FALLING OFF” THE BUS
The MCP40D17/18/19 expects to receive entire, valid
I2C commands and will assume any command not
defined as a valid command is due to a bus corruption
and will enter a passive high condition on the SDA
signal. All signals will be ignored until the next valid
START condition and CONTROL BYTE are received.
