5.1.5
DATA VALID
After the start condition, each bit of data in transmission
needs to be settled for time specified by tSU-DATA
before SCLK toggles from low-to-high (refer to the
Serial Interface Timing Specification).
5.1.6
ACKNOWLEDGE (ACK)
Each receiving device, when addressed, is obliged to
generate an acknowledge bit after the reception of
each byte. The master device must generate an extra
clock pulse for ACK to be recognized.
The acknowledging device has to pull down the SDA
line for tSU-DATA before the low-to-high transition of
SCLK from the Master and remains pulled down for
tH-DATA after high-to-low transition of SCLK.
During read, the master must signal an End-of-Data
(EOD) to the slave by not generating an ACK bit once
the last bit has been clocked out of the slave. In this
case, the slave will leave the data line released to
enable the master to generate the stop condition.
5.1.7
TIME OUT (MCP9802/03)
If the SCLK stays low for time specified by tOUT, the
MCP9802/03 resets the serial interface. This dictates
the minimum clock speed as specified in the SMBus
specification. The I2C bus specification does not limit
clock speed and, therefore, the master can hold the
clock indefinitely to process data (MCP9800/01 only).
