REQOP2:REQOP0: Request CAN Operation Mode bits
1xx = Request Configuration mode
011 = Request Listen Only mode
010 = Request Loopback mode
001 = Request Disable 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:
WIN2:WIN0: Window Address bits
This selects 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
ICODE2:ICODE0 bits can be copied to the WIN2:WIN0 bits to select the correct buffer. See
Example 23-2 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:
FP3:FP0: FIFO Read Pointer bits
These bits point to the message buffer to be read.
0111:0000 = Message buffer to be read
1111:1000 = Reserved
