Notes:
1. Clock high + Clock low must be less than or equal to 1/fC.
2. Value guaranteed by design and/or characterization, not 100% tested in production.
3. Only applicable as a constraint for a Write Status Register instruction when SRP[1:0]=(0,1).
4. For multiple bytes after first byte within a page, tBPN = tBP1 + tBP2 * N (typical) and tBPN = tBP1 + tBP2 * N (max), where N =
number of bytes programmed.
5. Max Value t with <50K cycles is 200ms and >50K & <100K cycles is 400ms.
