bit 2

Mode 0:

RXB0DBEN: Receive Buffer 0 Double-Buffer Enable bit

= Receive Buffer 0 overflow will write to Receive Buffer 1

= No Receive Buffer 0 overflow to Receive Buffer 1

Mode 1, 2:

FILHIT2: Filter Hit bit 2

This bit combines with other bits to form filter acceptance bits <4:0>.

bit 1

Mode 0:

JTOFF: Jump Table Offset bit (read-only copy of RXB0DBEN)

= Allows jump table offset between 6 and 7

= Allows jump table offset between 1 and 0

Note:

This bit allows same filter jump table for both RXB0CON and RXB1CON.

Mode 1, 2:

FILHIT1: Filter Hit bit 1

This bit combines with other bits to form filter acceptance bits <4:0>.

bit 0

Mode 0:

FILHIT0: Filter Hit bit 0

This bit indicates which acceptance filter enabled the message reception into Receive Buffer 0.

= Acceptance Filter 1 (RXF1)

= Acceptance Filter 0 (RXF0)

Mode 1, 2:

FILHIT0: Filter Hit bit 0

This bit, in combination with FILHIT<4:1>, indicates which acceptance filter enabled the

message reception into this receive buffer.

01111

= Acceptance Filter 15 (RXF15)

01110

= Acceptance Filter 14 (RXF14)

...

00000

= Acceptance Filter 0 (RXF0)

Legend:

U = Unimplemented bit, read as ‘0’

- n = Value at POR

C = Clearable bit

R = Readable bit

W = Writable bit

x = Bit is unknown

‘1’ = Bit is set

‘0’ = Bit is cleared
