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 SPICLK to the 50% level of the signal. Timings
2. The symbols used for timing specifications follow the pattern of t
3. All units of output delay must be enabled for 8309_output_port spimosi_lpgl0(SPI Master Mode)
4. delay units must not be enabled for Slave Mode.
