BIT NAME
FUNCTION
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
7~0
SADEN
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.

Reserved.
This bit disables the expression of the ALE signal on the device pin during all
on-board program and data memory accesses. External memory accesses will

0: ALE expression is enabled.
1: ALE expression is disabled and keep in logic high state.
