Dual UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
10.3 Addressing
Before any data is transmitted or received, the master must send the address of the
receiver via the SDA line. The first byte after the START condition carries the address of
the slave device and the read/write bit. Table 32 shows how the SC16IS752/SC16IS762’s
address can be selected by using A1 and A0 pins. For example, if these 2 pins are
connected to VDD, then the SC16IS752/SC16IS762’s address is set to 0x90, and the
master communicates with it through this address.
[1]
X = logic 0 for write cycle; X = logic 1 for read cycle.
10.4 Use of subaddresses
When a master communicates with the SC16IS752/SC16IS762 it must send a
subaddress in the byte following the slave address byte. This subaddress is the internal
address of the word the master wants to access for a single byte transfer, or the beginning
of a sequence of locations for a multi-byte transfer. A subaddress is an 8-bit byte. Unlike
the device address, it does not contain a direction (R/W) bit, and like any byte transferred
on the bus it must be followed by an acknowledge.
A register write cycle is shown in Figure 18. The START is followed by a slave address
byte with the direction bit set to ‘write’, a subaddress byte, a number of data bytes, and a
STOP signal. The subaddress indicates which register the master wants to access, and
the data bytes which follow will be written one after the other to the subaddress location.
Table 33 and Table 34 show the bits’ presentation at the subaddress byte for I2C-bus and
SPI interfaces. Bit 0 is not used, bits 2:1 select the channel, bits 6:3 select one of the
UART internal registers. Bit 7 is not used with the I2C-bus interface, but it is used by the
SPI interface to indicate a read or a write operation.
