Table 5.
The bus interface has a total of 3 read bytes. If a start of transmission is detected and the

the data is clocked out. If not, the internal clock is disabled and the data output will be
logic 1s (FFh).
Table 6.
The Dbus function becomes active when bit DBUS = 1 and when the maximum available
bytes are written in the write mode or when the maximum available bytes are read in the
read mode. At every start of an I
