22.1.16.1 SENTDATA/NEWDATA Bit
22.1.16.2 TRMACTIVE/INVALDATA Bit
22.1.16.3 MSGLOST Bit
22.1.16.4 REMACTIVE Bit

The SENTDATA/NEWDATA bit indicates that the CAN module has transmitted or received the CAN
message. Set the SENTDATA/NEWDATA bit to "0 " (not transmitted or not received) by program
before data transmission and reception is started. The SENTDATA/NEWDATA bit is not set to "0"
automatically. When the TRMACTIVE/INVALDATA bit is set to "1" (during transmission or storing
received data), the SENTDATA/NEWDATA bit cannot be set to "0".
The TRMACTIVE/INVALDATA bit indicates that the CAN module is transmitting or receiving a mes-
sage and accessing the message slot i. The TRMACTIVE/INVALDATA bit is set to "1" when the CAN
module is accessing the message slot and to "0 " when not accessing the message slot.
The MSGLOST bit is valid only when the message slot is set for reception. The MSGLOST bit is set to
"1" (overrun error occurred) when the message slot i is overwritten by a new received message while
the NEWDATA bit set to "1" (already received).
The MSGLOST bit is not automatically set to "0". Set to "0" (no overrun error occurred) by program.
The C0MCTL0 to C0MCTL15 registers all have the same function when the STATE_BASICCAN bit is
set to "0" (other than BasicCAN mode).
The REMACTIVE bit is set to "1" (remote frame) when the message slot i is set to transmit or receive
the remote frame. The REMACTIVE bit is set to "0" (data frame) after the remote frame has been
transmitted or received.
The functions of the C0MCTL14 and C0MCTL15 registers change when the STATE_BASICCAN bit is
set to "1" (BasicCAN mode). When the REMACTIVE bit is set to "0", this indicates that a message
stored into the message slot is the data frame. When the REMACTIVE bit is set to "1", this indicates a
message stored into the message slot is the remote frame.
