JTAG specifications 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 V
V
The Nexus AUX port runs up to 82 MHz. Set NPC_PCR[MCKO_DIV] to divide-by-two if the system frequency
is greater than 82 MHz.
MDO, MSEO, and EVTO data is held valid until the next MCKO low cycle occurs.
Limit the maximum frequency to approximately 16 MHz (V
specification for t
The RDY pin timing is asynchronous to MCKO and is guaranteed by design to function correctly.
