SPI outputs—Master mode (internal clock) delay
SPI outputs—Slave mode (external clock) delay
SPI inputs—Master mode (internal clock) input setup time
SPI inputs—Master mode (internal clock) input hold time
SPI inputs—Slave mode (external clock) input setup time
SPI inputs—Slave mode (external clock) input hold time
Notes:
1. Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal.
2. The symbols used for timing specifications follow the pattern of t
