Clockless register access allows a host device to access registers on the WINC device
while it is held in a reset state. This type of access can only be done using the
“internal register read” and “internal register write” commands. For Clockless access,
bit 15 of the Offset_addr in the command must be ‘1’
to differentiate between the Clockless and Clocked access mode.
For the Clockless register write, the protocol Host must wait for the response as
shown here:
For the Clockless register read, according to the interface, the protocol Client
may not send CRC16. One- or two-byte padding depends on three- or four-byte DMA
addresses.
