setup time (see Figure 4) before the next rising edge of
SCL during a bit read. The device shifts out each bit of
data on SDA at the falling edge of the previous SCL
pulse and the data bit is valid at the rising edge of the
current SCL pulse. Remember that the master gener-
ates all SCL clock pulses including when it is reading
bits from the slave.
Acknowledgement (ACK and NACK):
An Acknowledge-
ment (ACK) or Not Acknowledge (NACK) is always the
9th bit transmitted during a byte transfer. The device
receiving data (the master during a read or the slave
during a write operation) performs an ACK by transmit-
ting a zero during the 9th bit. A device performs a
NACK by transmitting a one during the 9th bit. Timing
(Figure 4) for the ACK and NACK is identical to all other
bit writes. An ACK is the acknowledgment that the
device is properly receiving data. A NACK is used to
terminate a read sequence or as an indication that the
device is not receiving data.
