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 SC16IS740/750/760’s
address can be selected by using A1 and A0 pins. For example, if these 2 pins are
connected to V
DD
, then the SC16IS740/750/760’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 SC16IS740/750/760 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.
Table 33
shows the breakdown of the subaddress (register address) byte. Bit 0 is not
used, bits [2:1] are both set to zeroes, bits [6:3] are used to select one of the device’s
internal registers, and bit 7 is not used.
A register write cycle is shown in
Figure 22
. 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.
