SADEN [7:0]
This register enables the Automatic Address Recognition feature of the Serial
port 0. When a bit in the SADEN is set to 1, the same bit location in SADDR
will be compared with the incoming serial data. When SADEN is 0, then the
bit becomes a "don't care" in the comparison. This register enables the
Automatic Address Recognition feature of the Serial port 0. When all the bits
of SADEN are 0, interrupt will occur for any incoming address.
