Good Example
Any address other than addresses 0h to 6h
permits of immediate reading or writing
without requiring a time span of 31
μ
s.
Bad Example (1): Where the CE pin is once driven low in the process of reading time data.
Bad Example (2): Where a time span of less than 31
μ
s is left until the start of the process of writing time data.
Bad Example (3): Where a time span of less than 61
μ
s is left between the adjacent processes of reading time data.
