SC16IS752; SC16IS762
Dual UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
The register read cycle (see Figure 19) commences in a similar manner, with the master
sending a slave address with the direction bit set to WRITE with a following subaddress.
Then, in order to reverse the direction of the transfer, the master issues a Repeated
START followed again by the device address, but this time with the direction bit set to
READ. The data bytes starting at the internal subaddress will be clocked out of the device,
each followed by a master-generated acknowledge. The last byte of the read cycle will be
followed by a negative acknowledge, signalling the end of transfer. The cycle is
terminated by a STOP signal.
