BIT NAME
FUNCTION
This register enables the Automatic Address Recognition feature of the serial port.
When a bit in SADEN is set to 1, the same bit in SADDR is compared to the
7~0 SADEN incoming serial data. When a bit in SADEN is set to 0, the same bit in SADDR is a
"don't care" value in the comparison. The serial port interrupt occurs only if all the
SADDR bits where SADEN is set to 1 match the incoming serial data.
