SPI / I2C Interface Timing

I001 tsCCL

Setup Time:

NCS/A1 hi → lo before SCLK lo → hi

INS/WKR = lo

I002 tsDCL

Setup Time:

MOSI/A0 stable before SCLK/SCL lo →

INS/WKR = lo

I003 thDCL

Hold Time:

MOSI/A0 stable after SCLK/SCL lo → hi

INS/WKR = lo

I004 tCLH

Signal Duration SCLK/SCL hi

INS/WKR = lo

I005 tCLI

Signal Duration SCLK/SCL lo

INS/WKR = lo

I006 thCLC

Hold Time: NCS/A1 lo after SCLK/SCL
