The RECSUCC bit is set to "1" when the CAN module has received data successfully. (Whether
is transmitted in loopback mode, the TRMSUCC bit is set to "1" and the RECSUCC bit is set to "0".
The RECSUCC bit is set to "0" when the CAN module has transmitted data successfully.
The TRMSTATE bit is set to "1" when the CAN module is performing as a transmit node.
The TRMSTATE bit is set to "0" when the CAN module is in a bus-idle state or starts performing as a
receive node.
The RECSTATE bit is set to "1" when the CAN module is performing as a receive node.
The RECSTATE bit is set to "0" when the CAN module is in a bus-idle state or starts performing as a
transmit node.
After both RESET1 and RESET0 bits are set to "1" (CAN module reset), the STATE_RESET bit is set
to "1" as soon as the CAN module is reset.
The STATE_RESET bit is set to "0" when the RESET1 and RESET0 bits are set to "0".
The STATE_ LOOPBACK bit is set to "1" when the CAN module is in loopback mode.
The STATE_LOOPBACK bit is set to "1" when the LOOPBACK bit in the C0CTLR0 register is set to "1"
(loop back function enabled).
The STATE_LOOPBACK bit is set to "0" when the LOOPBACK bit is set to "0" (loop back function
disabled).
The STATE_BASICCAN bit is set to "1" when the CAN module is in BasicCAN mode.
Refer to 23.1.1.3 BASICCAN bit for BasicCAN mode.
The STATE_BASICCAN bit is set to "0" when the BASICCAN bit is set to "0" (BasicCAN mode
function disabled).
The STATE_BASICCAN bit is set to "1" when the BASICCAN bit is set to "1" (BasicCAN mode
function enabled), the REMACTIVE bits in the C0MCTL14 and C0MCTL15 registers in the message
slots 14 and 15 are set to "0" (data frame received).
The STATE_BUSERROR bit is set to "1" when an CAN communication error is detected.
The STATE_BUSERROR bit is set to "0" when the CAN module has transmitted or received data
successfully. Whether a received message has been stored into the message slot or not is irrel-
evant.
