Freescale Semiconductor 21-13
21.3.2.4.2 FlexCAN Rx 14 Mask Register (RX14MASK)
The RX14MASK register has the same structure as the Rx global mask register and is used to mask
message buffer 14. Access to this register is unrestricted.
21.3.2.4.3 FlexCAN Rx 15 Mask Register (RX15MASK)
The RX15MASK register has the same structure as the Rx global mask register and is used to mask
message buffer 15. Access to this register is unrestricted.
28–18 MI28–MI18 Standard ID mask bits. These bits are the same mask bits for the Standard and Extended
Formats.
17–0 MI17–MI0 Extended ID mask bits. These bits are used to mask comparison only in Extended Format.
