Table 4. SPI timing specification
Status byte
During transfer of the register access byte,
command strobes, the first RAM address
byte and data transfer to the TXFIFO, the
CC2420
status byte is returned on the
SO
pin. The status byte contains 6 status bits
which are described in Table 5.
Issuing a
SNOP
(no operation) command
strobe may be used to read the status
byte. It may also be read during access to
