Single UART with I

C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
The number of data bytes transferred between the START and STOP condition from
transmitter to receiver is not limited. Each byte, which must be eight bits long, is
transferred serially with the most significant bit first, and is followed by an acknowledge bit
(see
Figure 14
). The clock pulse related to the acknowledge bit is generated by the
master. The device that acknowledges has to pull down the SDA line during the
acknowledge clock pulse, while the transmitting device releases this pulse (see
Figure 15
).
A slave receiver must generate an acknowledge after the reception of each byte, and a
master must generate one after the reception of each byte clocked out of the slave
transmitter.
