CAN0 Global Mask Register Extended ID2 (C0GMSKE2)

CAN0 Local Mask Register A Extended ID2 (C0LMSKAE2) <Address:H'0080 1034>

CAN0 Local Mask Register B Extended ID2 (C0LMSKBE2) <Address:H'0080 103C>
Three registers are used in acceptance filtering: Global Mask Register, Local Mask Register A, and
Local Mask Register B. The Global Mask Register is used for message slots 0-13, while Local
Mask Registers A and B are used for message slots 14 and 15, respectively.
• When a bit in this register is set to 0, its corresponding ID bit is masked (assumed to have
matched) during acceptance filtering.
• When a bit in this register is set to 1, its corresponding ID bit is compared with the receive ID
during acceptance filtering and when it matches the ID set for the message slot, the received
data is stored in it.
Note 1: EID0M corresponds to the MSB of extended ID.
Note 2: The Global Mask Register can only be changed when none of slots 0-13 have receive
requests set.
Note 3: The Local Mask Register A can only be changed when slot 14 does not have a receive
request set.
Note 4: The Local Mask Register B can only be changed when slot 15 does not have a receive
request set.
