31:24 TXERR -
After reading all messages and releasing their memory space with the command 'Release Receive Buffer,' this bit is cleared.
If there is not enough space to store the message within the Receive Buffer, that message is dropped and the Data Overrun condition is
signalled to the CPU in the moment this message becomes valid. If this message is not completed successfully (e.g. because of an
error), no overrun condition is signalled.
The Transmission Complete Status bit is set '0' (incomplete) whenever the Transmission Request bit or the Self Reception Request bit
is set '1' at least for one of the three Transmit Buffers. The Transmission Complete Status bit will remain '0' until all messages are
transmitted successfully.
If both the Receive Status and the Transmit Status bits are '0' (idle), the CAN-Bus is idle. If both bits are set, the controller is waiting to
become idle again. After hardware reset 11 consecutive recessive bits have to be detected until idle status is reached. After Bus-off this
will take 128 times of 11 consecutive recessive bits.
Errors detected during reception or transmission will effect the error counters according to the CAN specification. The Error Status bit is
set when at least one of the error counters has reached or exceeded the Error Warning Limit. An Error Warning Interrupt is generated, if
enabled. The default value of the Error Warning Limit after hardware reset is 96 decimal, see also
Register (CAN1EWL - 0xE004 4018, CAN2EWL - 0xE004
Mode bit '1' (present) and an Error Warning Interrupt is generated, if enabled. Afterwards the Transmit Error Counter is set to '127', and
the Receive Error Counter is cleared. It will stay in this mode until the CPU clears the Reset Mode bit. Once this is completed the CAN
Controller will wait the minimum protocol-defined time (128 occurrences of the Bus-Free signal) counting down the Transmit Error
Counter. After that, the Bus Status bit is cleared (Bus-On), the Error Status bit is set '0' (ok), the Error Counters are reset, and an Error
Warning Interrupt is generated, if enabled. Reading the TX Error Counter during this time gives information about the status of the
Bus-Off recovery.

RX error counter
The RX Error Counter Register, which is part of the Status Register, reflects the current
value of the Receive Error Counter. After hardware reset this register is initialized to 0. In
Operating Mode this register appears to the CPU as a read only memory. A write access
to this register is possible only in Reset Mode. If a Bus Off event occurs, the RX Error
Counter is initialized to 0. As long as Bus Off is valid, writing to this register has no
effect.The Rx Error Counter is determined as follows:
Function
Receive Status.
The CAN controller is idle.
The CAN controller is receiving a message.
Transmit Status.
The CAN controller is idle.
The CAN controller is sending a message.
Error Status.
Both error counters are below the Error Warning Limit.
One or both of the Transmit and Receive Error Counters has reached the
limit set in the Error Warning Limit register.
Bus Status.
The CAN Controller is involved in bus activities
The CAN controller is currently not involved/prohibited from bus activity
because the Transmit Error Counter reached its limiting value of 255.
Reserved, user software should not write ones to reserved bits. The value
read from a reserved bit is not defined.
The current value of the Rx Error Counter (an 8 - bit value).
The current value of the Tx Error Counter (an 8 - bit value).
