HI-3585 SPI COMMANDS

For the HI-3585, each SPI read or write operation begins with an

8-bit command byte transferred from the host to the device after

assertion of

. Since HI-3585 command byte reception is half-

duplex, the host discards the dummy byte it receives while

serially transmitting the command byte.

Figures 5 and 6 show read and write timing as it appears for a

single-byte and dual-byte register operation. The command byte

is immediately followed by a data byte comprising the 8-bit data

word read or written. For a single register read or write,

is

negated after the data byte is transferred.

Multiple byte read or write cycles may be performed by

transferring more than one byte before

is negated. Table 1

defines the required number of bytes for each instruction.

Note: SPI Instruction op-codes not shown in Tables 1 are

“reserved” and must not be used. Further, these op-codes will

not provide meaningful data in response to read commands.

;

must be

negated after the command, then reasserted for the following

Read or Write command.

Two instruction bytes cannot be “chained”
