IO Flags
The host system is always the bus master, so before any IO transaction, the system must first send an 8-bit flag
indicate the IO operation that is to be performed, as follows:
All other values are reserved and will be ignored.

DC Parameters
Meaning
After this flag, the system starts sending a command block to the chip. The first bit of the block can
follow immediately after the last bit of the flag.
After a turn-around delay, the chip will start transmitting the response for a previously transmitted
command block.
Upon receipt of a sleep flag, the chip will enter a low power mode until the next Wake token is
received.
