RDY valid to MCKO 5
——
1 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 VDD = 1.35–1.65 V, VDDE = 2.25–3.6 V,
VDD33 and VDDSYN = 3.0–3.6 V, TA = TL to TH, and CL = 30 pF with DSC = 0b10.
2 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.
3 MDO, MSEO, and EVTO data is held valid until the next MCKO low cycle occurs.
4 Limit the maximum frequency to approximately 16 MHz (V
DDE = 2.25–3.0 V) or 20 MHz (VDDE = 3.0–3.6 V) to meet the timing
specification for tJOV of [0.2 x tJCYC] as outlined in the IEEE-ISTO 5001-2003 specification.
5 The RDY pin timing is asynchronous to MCKO and is guaranteed by design to function correctly.
