tCSIGNORE is defined as "SCLK falling edge to CS ignore", but it is very clearly drawn to the middle of an SCLK cycle in Figures 62 and 63.
Can someone please tell me which one is correct?
Also, can someone tell me why tCSIGNORE is needed at all? It looks like the falling edge of SCLK is already constrained by the tCSS (chip select falling to SCLK falling setup time), so as long as it isn't violated tCSIGNORE would be redundant. Am I missing something?
Thanks
