(1) If an external clock is chosen, this information is latched internally by setting pin 7 (PTC) LOW
(2) 1-byte programming.
(3) 2-byte programming.
(4) One page (8 byte) programming.
PTC
after transmission of the eighth bit 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.
