Note 3: Parameters are 100% production tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 4: Guaranteed by bench testing. Limits are not production tested.
Note 5: At VL = 1.4V to 2.5V, derate all the SPI timing characteristics by 50%. Not production tested.
Note 6: The minimum period is derived from SPI timing parameters.
Note 7: Time-to-exit suspend is dependent on the crystal used.
