(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) tPUR and tPUW are delays required from the time VCC is stable until the specified operation can be initiated.

ms
The write cycle is the time from a valid stop condition of a write sequence to the end of the internal program/erase
cycle. During the write cycle, the bus interface circuits are disabled, SDA is allowed to remain high, and the device
does not respond to its slave address.
