The following bus protocol has been defined:
Data transfer can be initiated only when the bus is
not busy.
During data transfer, the data line must remain sta-
ble whenever the clock line is high. Changes in the
data line while the clock line is high are interpreted
as control signals.
Accordingly, the following bus conditions have been
defined:
Bus Not Busy: Both data and clock lines remain
high.
Start Data Transfer: A change in the state of the
data line from high to low while the clock is high
defines a start condition.
Stop Data Transfer: A change in the state of the
data line from low to high while the clock line is
high defines the stop condition.
Data Valid: The state of the data line represents
valid data when, after a start condition, the data line
is stable for the duration of the high period of the
clock signal. The data on the line can be changed
during the low period of the clock signal. There is
