Program the CAN message 15 mask (CAN_MSK15) register to mask ("don't care") specific message

identifier bits for message 15 in addition to those bits masked by a global mask (CAN_EGMSK or

NOTE: Setting a CAN_MSK15 bit in any position that is cleared in the global mask register has no

effect. The message 15 mask is ANDed with the global mask, so any "don't care" bits

defined in a global mask are also "don't care" bits for message 15.

12.5 CONFIGURING MESSAGE OBJECTS

Each message object consists of a configuration register, a message identifier, control registers,

and data registers (from zero to eight bytes of data). This section explains how to configure mes-

sage objects and determine their status.

These bits individually mask incoming message identifier (ID) bits.

0 = mask the ID bit (accept either "0" or "1")

1 = accept only an exact match

Reserved. These bits are undefined; for compatibility with future devices,

do not modify these bits.

These bits individually mask incoming message identifier (ID) bits.

0 = mask the ID bit (accept either "0" or "1")
