bit 7

bit 0

bit 7-0

SID10:SID3: Standard Identifier Filter bits (if EXIDEN = 0)

Extended Identifier Filter bits EID28:EID21 (if EXIDEN = 1).

Note 1: Registers RXF6SIDH:RXF15SIDH are available in Mode 1 and 2 only.

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 4

Unimplemented: Read as ‘0’

bit 3

EXIDEN: Extended Identifier Filter Enable bit(2)

= Filter will only accept extended ID messages

= Filter will only accept standard ID messages

bit 2

Unimplemented: Read as ‘0’

bit 1-0

EID17:EID16: Extended Identifier Filter bits

Note 1: Registers RXF6SIDL:RXF15SIDL are available in Mode 1 and 2 only.

2: In Mode 0, this bit must be set/cleared as required, irrespective of corresponding

mask register value.
