Note 1: These parameters are characterized, but are not tested in manufacturing.

2: Data in “Typical” column is at 3.3V, +25°C unless otherwise stated.

3: The minimum clock period for SCKx is 111 ns. The clock generated in Master mode must not violate this

specification.

4: Assumes 50 pF load on all SPIx pins.

5: Pertaining to SPI3: dsPIC33EPXXXGS702, dsPIC33EPXXXGSX04 and dsPIC33EPXXXGSX05 devices

with a remappable SCK3 pin.
