REQOP<2:0>: Request CAN Operation Mode bits
1xx = Request Configuration mode
011 = Request Listen Only mode
010 = Request Loopback mode
001 = Disabled/Sleep mode
000 = Request Normal mode
ABAT: Abort All Pending Transmissions bit
1 = Abort all pending transmissions (in all transmit buffers)
0 = Transmissions proceeding as normal
Mode 0:
WIN<2:0>: Window Address bits
These bits select which of the CAN buffers to switch into the Access Bank area. This allows access to the
buffer registers from any data memory bank. After a frame has caused an interrupt, the ICODE<3:0> bits
can be copied to the WIN<2:0> bits to select the correct buffer. See Example 24-2 for a code example.
111 = Receive Buffer 0
110 = Receive Buffer 0
101 = Receive Buffer 1
100 = Transmit Buffer 0
011 = Transmit Buffer 1
010 = Transmit Buffer 2
001 = Receive Buffer 0
000 = Receive Buffer 0
Unimplemented: Read as ‘0’
Mode 1:
Unimplemented: Read as ‘0’
Mode 2:
FP<3:0>: FIFO Read Pointer bits
These bits point to the message buffer to be read.
0000 = Receive Message Buffer 0
0001 = Receive Message Buffer 1
0010 = Receive Message Buffer 2
0011 = Receive Message Buffer 3
0100 = Receive Message Buffer 4
