BUF63M –
BUF32M
Buffer MB_i Mask
Each bit enables or disables the respective FlexCAN Message Buffer (MB32 to MB63) Interrupt.
1 = The corresponding buffer Interrupt is enabled
0 = The corresponding buffer Interrupt is disabled
Note: Setting or clearing a bit in the IMRH register can assert or negate an interrupt request, if the
corresponding IFRH bit is set.
18.3.4.10 Interrupt Mask Register Low (IMRL)
This register allows to enable or disable any number of a range of 32 Message Buffer Interrupts. It contains
one interrupt mask bit per buffer, enabling the CPU to determine which buffer generates an interrupt after
a successful transmission or reception (i.e., when the corresponding IFRL bit is set).

BUF31M–BUF0M — Buffer MB_i Mask
Each bit enables or disables the respective FlexCAN Message Buffer (MB0 to MB31) Interrupt.
1 = The corresponding buffer Interrupt is enabled
0 = The corresponding buffer Interrupt is disabled
Note: Setting or clearing a bit in the IMRL register can assert or negate an interrupt request, if the
corresponding IFRL bit is set.
18.3.4.11 Interrupt Flag Register High (IFRH)
This register defines the flags for 32 Message Buffer interrupts. It contains one interrupt flag bit per buffer.
Each successful transmission or reception sets the corresponding IFRH bit. If the corresponding IMRH bit
