Notes to
(1) The minimum time corresponds to the maximum error detection clock frequency and may vary with different processes, voltages, and
(2) The maximum time corresponds to the minimum error detection clock frequency and may vary with different PVT.
(3) Only applicable for device with 1.2-V core voltage
(4) Only applicable for the F484 device package.
