assumes that the supplies are fully ramped to their 1.3 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 startup 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 RESET to be held low a minimum of four CLKIN cycles in order to properly initialize and propagate
default states at all I/O pins.

The 4096 cycle count depends on t
srst
specification. If setup time is not met, 1 additional CLKIN cycle may be added to the core reset time, resulting in 4097 cycles maximum.
