JTAG specifications in this table apply when used for debug functionality. All Nexus timing relative to MCKO is measured from
50% of MCKO and 50% of the respective signal. Nexus timing specified at VDD = 1.35V to 1.65V, VDDE = 2.25V to 3.6V,
VDD33 and VDDSYN = 3.0V to 3.6V, T
The Nexus AUX port can only run up to 82MHz. The NPC_PCR[MCKO_DIV] must be set to divide by 2 if the system frequency
is above 82MHz
MDO, MSEO, and EVTO data is held valid until next MCKO low cycle.
The maximum frequency must be limited to approximately 16 MHz (VDDE= 2.25 to 3.0 volts) or 22 MHz (VDDE= 3.0 to 3.6
volts) to meet the timing specification for t
The RDY pin timing is asynchronous to MCKO. The timing is guaranteed by design to function correctly.
