AR10

: Address Recognition10

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 receivedframe is not compared to AF0/7 bits of AFRDR

AR11

: Address Recognition 11

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

: Address Recognition 20

AR20 = 1, Secondbyte after opening flag of received frame is comparedto AF8/15bits of AFRDR

AR20 = 0, Second byte after opening flag of received frame is not compared to AF8/15 bits of

AFRDR Register.

AR21

: Address Recognition 21

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.

Conditions to Receive a Frame

AR21 AR20 AR11

AR10

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.

The value of the second received byte must be equal either to that of AF8/15

or 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 either to that of AF8/15

or to all ”1”s.

The value of the first received byte must be equal to ”1” and the value of the

second received byte must be equal either to that of AF8/15 or to all ”1”s.

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 either to that

of AF8/15 or to all ”1”s.
