Comment
A.MOAR[28:18] < B.MOAR[28:18]
(11-bit standard identifier of A less than
11-bit standard identifier of B)
Messages with lower standard identifier
have higher priority than messages with
higher standard identifier. MOAR[28] is the
most significant bit (MSB) of the standard
identifier. MOAR[18] is the least significant
bit of the standard identifier.
A.MOAR[28:18] = B.MOAR[28:18]
A.MOAR.IDE = 0 (send Standard Frame)
B.MOAR.IDE = 1 (send Extended Frame)
Standard Frames have higher transmit
priority than Extended Frames with equal
standard identifier.
A.MOAR[28:18] = B.MOAR[28:18]
A.MOAR.IDE = B.MOAR.IDE = 0
A.MOCTR.DIR = 1 (send data frame)
B.MOCTR.DIR = 0 (send Remote Fame)
Standard data frames have higher transmit
priority than standard remote frames with
equal identifier.
A.MOAR[28:0] = B.MOAR[28:0]
A.MOAR.IDE = B.MOAR.IDE = 1
A.MOCTR.DIR = 1 (send data frame)
B.MOCTR.DIR = 0 (send remote frame)
Extended data frames have higher transmit
priority than Extended remote frames with
equal identifier.
A.MOAR[28:0] < B.MOAR[28:0]
A.MOAR.IDE = B.MOAR.IDE = 1
(29-bit identifier)
Extended Frames with lower identifier have
higher transmit priority than Extended
Frames with higher identifier. MOAR[28] is
the most significant bit (MSB) of the overall
identifier (standard identifier MOAR[28:18]
and identifier extension MOAR[17:0]).
MOAR[0] is the least significant bit (LSB) of
the overall identifier.
