assumes that the supplies are fully ramped to their 1.2 volt rails and 3.3 volt rails. Voltage ramp rates can vary from microseconds to hundreds of
milliseconds depending on the design of the power supply subsystem.

Assumes a stable CLKIN signal, after meeting worst-case start-up timing of crystal oscillators. Refer to your crystal oscillator manufacturer’s data sheet for start-up time.
Assume a 25 ms maximum oscillator start-up time if using the XTAL pin and internal oscillator circuit in conjunction with an external crystal.

Applies after the power-up sequence is complete. Subsequent resets require a minimum of 4 CLKIN cycles for RESET to be held low in order to properly initialize and
propagate default states at all I/O pins.

specification in
Table 14
. If setup time is not met, 1 additional CLKIN cycle may be added to the core reset time, resulting in 4097
cycles maximum.
