Figure 8. Register Read Access
Similarly, the configuration registers of the RFM67W can be read by issuing an ‘address read-byte’ (see Figure 8)
the corresponding register contents are then transferred over the MISO line. As above, the contents of each subsequent
register can be transferred by holding the NSS input low.
A summary of all of the registers of the RFM67W are given in Table 11, this is followed by detailed descriptions of each of
the registers in Table 12.
