1. tCH + tCL must be greater than or equal to 1/ fC
2. Value guaranteed by characterization, not 100% tested in production.
3. Expressed as a slew-rate.
4. Only applicable as a constraint for a WRSR instruction when SRWD is set at 1.
Note:
*40 MHz = max frequency device operation in extended Vcc range 2.3 to 2.7 V.
