Table 2.63

SPI timing (4 of 5)

Conditions:

1. High-speed high drive output is selected in the Port Drive Capability bit in the PmnPFS register for the following pins:

RSPCLKA_B, RSPCLKB_B.

For other pins, high drive output is selected in the Port Drive Capability bit in the PmnPFS register.

2. Use pins that have a letter appended to their names, for instance “_A” or “_B” to indicate group membership.

3. Load capacitance C = 15pF is applied to the VCC/VCC2 condition “3.00 V or above”.
