AC ELECTRICAL CHARACTERISTICS
Notes:
1. An initial pause of 100us is required after power up, followed by two AUTO REFRESH commands, before proper device operation
2. Measured with t
3. The reference level is 1.5V when measuring input signal timing. Rise/fall times are measured between V
6. CLK must be toggled a minimum of two times during this period.
