F81216AD
9-bit Mode Slave Address Register  Index F4h
Bit
Name
7-0 ^SADDR_URB
R/W Default
Description
R/W 00h ^{This byte accompanying with SADEN_URB 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:
3. given address: If bit n of SADEN_URB is “0”, then the corresponding bit of
SADDR_URB is don’t care.
4. broadcast address: If bit n of ored SADDR_URB and SADEN_URB is “0”,
don’t care that bit. The remaining bit which is “1” is compared to the
received address.
Ex.
SADDR_URB
0101_1100b
SADEN_URB
1111_1001b
Given Address
0101_1xx0b
Broadcast Address
1111_11x1b
9-bit Mode Slave Address Mask Register  Index F5h
Bit
Name
7-0 ^SADEN_URB
R/W Default
Description
R/W 00h ^{This byte accompanying with SADDR_URB will determine the given address}
and broadcast address in 9-bit mode. The UART_URB will response to both
given and broadcast address.
Follow the description to determine the given address and broadcast address:
1. given address: If bit n of SADEN_URB is “0”, then the corresponding bit
of SADDR_URB is don’t care.
2. broadcast address: If bit n of ored SADDR_URB and SADEN_URB is “0”,
don’t care that bit. The remaining bit which is “1” is compared to the
received address.
Ex.
SADDR_URB
0101_1100b
SADEN_URB
1111_1001b
Given Address
0101_1xx0b
Broadcast Address
1111_11x1b
