SPI Read
Figure 1 shows a single-byte read transaction. In this
example, a single byte is read from the slave by the master.
The master first asserts CSB, begins driving SDA with the
R/Wb bit having value of 1 indicating this a read transaction
and starts toggling SCLK. The slave samples the bits on
SDA on the rising edge of SCLK. After the R/Wb bit, the
master outputs the 3-bit register addresses starting with the
most significant bit following which the master releases the
SDA line. The slave then starts driving SDA and outputs
the single byte that was requested by the master. After the
last bit has been output, the slave three-states SDA on the
rising edge of CSB that ends the transaction.
SPI Write
Figure 2 shows a single-byte write transaction. In this
example, a single byte is written to the slave by the
master. The master first asserts CSB, begins driving SDA
with the R/Wb bit having value of 0 indicating this a write
transaction and starts toggling SCLK. The slave samples
the bits on SDA on the rising edge of SCLK. After the R/
Wb bit, the master outputs the 3-bit register addresses
starting with the most significant bit and then the 8-bit data
starting with the most significant bit. The internal registers
are updated on the 12th rising edge of SCLK.
