FDCAN extended ID and mask register

Type Definitions

EIDM_R

Field EIDM reader - Extended ID mask For acceptance filtering of extended frames the Extended ID AND Mask is AND-ed with the Message ID of a received frame. Intended for masking of 29-bit IDs in SAE J1939. With the reset value of all bits set to 1 the mask is not active. These are protected write (P) bits, which means that write access by the bits is possible only when the bit 1 [CCE] and bit 0 [INIT] of CCCR register are set to 1.
