Timing specified for equal load on all SPI output pins. Avoid asymmetric load.
These values apply for carefully designed PCB layouts with capacitors that match the crystal/resonator requirements.
Only applies if EXTAL is externally driven.
the timing diagram for master mode with transmission format CPHA = 0 is depicted.
