Section 14 Controller Area Network (HCAN)
14.8.5
In the case of error active and error passive, REC and TEC perform count up and down normally.
In the bus-off state, 11-bit recessive sequences are counted (REC + 1) using REC. When REC
reaches 96 during the count, IRR4 and GSR1 are set.
14.8.6
Byte or word access can be performed for all HCAN registers. Longword access should be
avoided.
14.8.7
In medium-speed mode, the HCAN registers cannot be read/written.
14.8.8
All HCAN registers are initialized in hardware standby mode and software standby mode.
14.8.9
Since the HCAN status flag is cleared by writing 1, do not use the bit manipulation instructions to
clear the flag. To clear the flag, use the MOV instructions and write 1 only to the bit to be cleared.
