Description

Control 2 Register

Fields

EACEN

This bit controls the comparison of IDE and RTR bits within Rx Mailboxes filters with their corresponding bits in the incoming frame by the matching process

0 (EACEN_0): Rx Mailbox filter’s IDE bit is always compared and RTR is never compared despite mask bits.

1 (EACEN_1): Enables the comparison of both Rx Mailbox filter’s IDE and RTR bit with their corresponding bits within the incoming frame. Mask bits do apply.

RRS

If this bit is asserted Remote Request Frame is submitted to a matching process and stored in the corresponding Message Buffer in the same fashion of a Data Frame

0 (RRS_0): Remote Response Frame is generated

1 (RRS_1): Remote Request Frame is stored

MRP

If this bit is set the matching process starts from the Mailboxes and if no match occurs the matching continues on the Rx FIFO

0 (MRP_0): Matching starts from Rx FIFO and continues on Mailboxes

1 (MRP_1): Matching starts from Mailboxes and continues on Rx FIFO

TASD

This 5-bit field indicates how many CAN bits the Tx arbitration process start point can be delayed from the first bit of CRC field on CAN bus

RFFN

This 4-bit field defines the number of Rx FIFO filters according to

WRMFRZ

Enable unrestricted write access to FlexCAN memory in Freeze mode

0 (WRMFRZ_0): Keep the write access restricted in some regions of FlexCAN memory

1 (WRMFRZ_1): Enable unrestricted write access to FlexCAN memory
