Fig.14 External clock.
(1) If an external clock is chosen, this information is latched internally by setting pin 7 (PTC) LOW after transmission of the eighth bits of the word
address (negative edge of SCL). Thus the state of pin 7 may be previously undefined. Leaving pin 7 LOW causes a higher standby current.
(2) 1-byte programming.
(3) 2-byte programming.
(4) One page (8 bytes) programming.
