4.1.1. Command Timing
8558E–SMEM–8/10
IO Flags
The host system is always the bus master, so before any IO transaction, the system must first send an 8-bit flag
to the chip to indicate the IO operation that is to be performed, as follows:
All other values are reserved and will be ignored.
After a command flag is transmitted, a command block should be sent to the chip. During parsing of the
parameters and subsequent execution of a properly received command, the chip will be busy and not respond to
transitions on the signal pin. The delays for these operations are listed in the table below:

is used as shorthand for the delay corresponding to whatever command has been sent to
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.
