7-0 ^SADDR_URC
F81216AD
R/W 00h ^{This byte accompanying with SADEN_URC will determine the given address}
and broadcast address in 9-bit mode. The UART will response to both given
and broadcast address.
Follow the description to determine the given address and broadcast address:
5. given address: If bit n of SADEN_URC is “0”, then the corresponding bit of
SADDR_URC is don’t care.
6. broadcast address: If bit n of ored SADDR_URC and SADEN_URC is “0”,
don’t care that bit. The remaining bit which is “1” is compared to the
received address.
Ex.
SADDR_URC
0101_1100b
SADEN_URC
1111_1001b
Given Address
0101_1xx0b
Broadcast Address
1111_11x1b

given and broadcast address.
Follow the description to determine the given address and broadcast address:
1. given address: If bit n of SADEN_URC is “0”, then the corresponding bit
of SADDR_URC is don’t care.
3. broadcast address: If bit n of ored SADDR_URC and SADEN_URC is “0”,
don’t care that bit. The remaining bit which is “1” is compared to the
received address.
Ex.
SADDR_URC
0101_1100b
SADEN_URC
1111_1001b
Given Address
0101_1xx0b
Broadcast Address
