SPI slave select signals

Hi all,

In an SPI interface i have got 4 slaves and one master What i wanted to know is wether the master can assert two slave selects(SS_N) simultaneously OR is there a restriction that master can assert only one slave select.

Does SPI standard dictate anything!!!

Any comments on this would be appreciated.

Regards, Praveen

SPI sends and receives simultaneously. If you only want to send data, and make no connections to the slave devices output, you can send data to as many (identical) slave devices as you want.

Most SPI-devices have a push-pull-output, so I won't do that...
