AR21 : Address Recognition 21
: Address Recognition 11
AR10 = 1, First byte after opening flag of received frame is compared to AF0/7 bits of AFRDR.
If the first byte received and AF0/7 bits are not identical the frame is ignored.
AR10 = 0, First byte after opening flag of received frame is not compared to AF0/7 bits of AFRDR
Register.
AR11 = 1, First byte after opening flag of received frame is compared to all "1"s.If the first byte
received is not all "1"s the frame is ignored.
AR11 = 0, First byte after opening flag of received frame is not compared to all "1"s.
AR20 = 1, Second byte after opening flag of received frame is compared to AF8/15 bits of AFRDR
Register. If the second byte received and AF8/15 bits are not identical the frame is ignored.
AR20 = 0, Second byte after opening flag of received frame is not compared to AF8/15 bits of
AFRDR Register.
AR21 = 1, Second byte after opening flag of received frame is compared to all "1"s. If the
Second byte received is not all "1"s the frame is ignored.
AR21 = 0, Second byte after opening flag of received frame is not compared to all "1"s.

Each frame is received without condition.
Only value of the first received byte must be equal to that of AF0/7 bits.
Only value of the first received byte must be equal to all "1"s.
The value of the first received byte must be equal either to that of AF0/7 or
to all "1"s.
Only value of the second received byte must be equal to that of AF8/15 bits.
The value of the first received byte must be equal to that of AF0/7 bits and
the value of the second received byte must be equal to that of AF8/15 bits.
The value of first received byte is must be equal to all "1"s and the value of
second received byte must be equal to that of AF8/15 bits.
The value of the first received byte must be equal either to that of AF0/7 or
to all "1"s and the value of the second received byte must be equal to that
of AF8/15 bits.
Only the value of the second received byte must be equal to all "1"s.
The value of the first received byte must be equal to that of AF0/7 bits and
the value of the second received byte must be equal to all "1"s.
The value of the first received byte must be equal to all "1"s and the value of
the second received byte must be equal to "1" also.
The value of the first received byte must be equal either to that of AF0/7 or
to "1" and the value of the second received byte must be equal to all "1"s.
