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.

Note:

(1) This parameter is tested initially and after a design or process change that affects the parameter.

(2) tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated.
