TECHNICAL DATA
NOTES:
1. Input clocks with duty cycles other than 50% affect bus performance.
2. Indicates a parameter affected by clock stretching. Add n(tcyc) to parameter value, where:
n = 1, 2, or 3 depending on values written to CSSTRH register.
3. All timing is shown with respect to 20% VDD and 70% VDD, unless otherwise noted.
