EBI Timings
See EBI I/O lines description for more details.
Note:
1. The maximum frequency of the SMC interface is the same as the max frequency for the HSB.
Note:
1. These values are based on simulation and characterization of other AVR microcontrollers manufactured in the same pro-
cess technology. These values are not covered by test limits in production.
2. hold length = total cycle duration - setup duration - pulse duration. “hold length” is for “ncs rd hold length” or “nrd hold length”.
