How NI 8451 support 93LC46 ( non - 8 bit command) ?

[BoltDog]

Hi, everyone

I  use NI 845x spi  to commuicate with 93LC46 on my board, it doesn't work,

the 93LC46 's command is 10 bits, it's not a completed byte or word, and

the api ni845xSpiWriteRead can only send bytes.

I've testted NI 845x with other spi devices those command is a byte or a word, it's ok.

Does someone know this problem? Thanks.
