Dual Output Read
The SPI Dual Output Read instruction inputs the instruction code and the address and dummy bytes one bit per clock
and outputs the data two bits per clock. This instruction is supported in SPI bus protocol only with clock frequencies up
to 80 MHz. This instruction is not supported in SQI bus protocol.
The SPI slave interface is selected by first bringing SCS# active. The 8-bit SDOR instruction, 3Bh, is input into the SIO[0]
pin, followed by the two address bytes and 1 dummy byte. The address bytes specify a BYTE address within the device.
On the falling clock edge following the rising edge of the last dummy di-bit, the SIO[1:0] pins are driven starting with the
msbs of the LSB of the selected register. The remaining register di-bits are shifted out on subsequent falling clock edges.
The SCS# input is brought inactive to conclude the cycle. The SIO[1:0] pins are three-stated at this time.
Figure 10-7 illustrates a typical single and multiple register dual output read.
