Description
General interrupt flag
This status bit is the image of all the CAN controller interrupts sent
to the interrupt controller.
It can be used in the case of the polling method.
Reserved
The values read from this bit is indeterminate. Do not set this bit.
Overrun CAN Timer
This status bit is set when the CAN timer switches 0xFFFF to
0x0000.
If the bit ETIM in the IE1 register is set, an interrupt is generated.
Clear this bit in order to reset the interrupt.
Overrun BUFFER
0 - no interrupt.
1 - IT turned on
This bit is set when the buffer is full.
bit resetable by user.
See Figure 39.
Stuff Error General
Detection of more than five consecutive bits with the same polarity.
This flag can generate an interrupt. resetable by user.
CRC Error General
The receiver performs a CRC check on each destuffed received
message from the start of frame up to the data field.
If this checking does not match with the destuffed CRC field, a
CRC error is set.
This flag can generate an interrupt. resetable by user.
Form Error General
The form error results from one or more violations of the fixed form
in the following bit fields:
CRC delimiter
acknowledgment delimiter
end_of_frame
This flag can generate an interrupt. resetable by user.
Acknowledgment Error General
No detection of the dominant bit in the acknowledge slot.
This flag can generate an interrupt. resetable by user.
