5.6.5
The Master (microcontroller) and the slave (MCP3424)
use an acknowledge pulse as a hand shake of
communication for each byte. The ninth clock pulse of
each byte is used for the acknowledgement. The clock
pulse is always provided by the Master (microcontrol-
ler) and the acknowledgement is issued by the
receiving device of the byte (Note: The transmitting
device must release the SDA line during the acknowl-
edge pulse.). The acknowledgement is achieved by
pulling-down the SDA line “LOW” during the 9th clock
pulse by the receiving device.

DATA
During reads, the Master (microcontroller) can
terminate the current read operation by not providing
an acknowledge bit on the last byte that has been
clocked out from the MCP3424. In this case, the
MCP3424 releases the SDA line to allow the Master
(microcontroller) to generate a STOP or repeated
START condition.
