To read back data from the transceiver, the R/W bit must be set to 0 followed by the 7-bit address of the
register from which to read. The 8 bit DATA field following the 7-bit ADDR field is ignored on the MOSI pin
when R/W = 0. The next eight negative edge transitions of the SCK signal will clock out the contents of the
selected register. The data read from the selected register will be available on the MISO output. The READ
function is shown in Figure 22.3. After the READ function is completed the MISO signal will remain at
either a logic 1 or logic 0 state depending on the last data bit clocked out (D0). When NSS goes high the
MISO output pin will be pulled high by internal pullup.
