The program cycle time is the time from a valid stop

condition of a write sequence to the end of the internal

erase/program cycle. During the program cycle, the

X24F064/032/016 bus interface circuits are disabled,

SDA is allowed to remain HIGH, and the device does

not respond to its slave address.
