Slave Address Mask Enable Register 0. This register functions as a mask
when comparing serial port 0 addresses for automatic address recognition.
When a bit in this register is set, the corresponding bit location in the SADDR0
register will be exactly compared with the incoming serial port 0 data to
determine if a receiver interrupt should be generated. When a bit in this register
is cleared, the corresponding bit in the SADDR0 register becomes a don‘t care
and is not compared against the incoming data. All incoming data will generate
a receiver interrupt when this register is cleared.
Slave Address Mask Enable Register 1. This register functions as a mask
when comparing serial port 1 addresses for automatic address recognition. When
a bit in this register is set, the corresponding bit location in the SADDR1 register
will be exactly compared with the incoming serial port 1 data to determine if a
receiver interrupt should be generated. When a bit in this register is cleared, the
corresponding bit in the SADDR1 register becomes a don’t care and is not
compared against the incoming data. All incoming data will generate a receiver
interrupt when this register is cleared.
