product that is communicating. If EEPROM is outputting a low level to the SDA0 pin, for example, set the
SCL0 pin in the output port mode, and output a clock pulse from the output port until the SDA0 pin is
constantly at high level.
Conform to the specifications of the product that is communicating, with respect to the transmission and
reception formats.
