I
Acknowledge may be enabled and disabled by
software.
The I
dress can be selected by software.
The speed of the I
between Standard (up to 100KHz) and Fast I
(up to 400KHz).
SDA/SCL Line Control
Transmitter mode: the interface holds the clock
line low before transmission to wait for the micro-
controller to write the byte in the Data Register.
Receiver mode: the interface holds the clock line
low after reception to wait for the microcontroller to
read the byte in the Data Register.
