Bit 7 = WKUIE Wake-Up Interrupt Enable
Bits 6:4 = reserved. Forced to 0 by hardware.
Bit 3 = FOVIE FIFO Overrun Interrupt Enable\
Bit 2 = FFIE FIFO Full Interrupt Enable
Bit 1 = FMPIE FIFO Message Pending Interrupt Enable
Bit 0 = TMEIE Transmit Mailbox Empty Interrupt Enable
CAN error status register (CESR)
Read/ write
Reset value: 0000 0000 (00h)
Bit 7 = reserved. Forced to 0 by hardware.
Bits 6:4 = LEC[2:0] Last Error Code
Read/ set/ clear
This field holds a code which indicates the type of the last error detected on the CAN bus. If
a message has been transferred (reception or transmission) without error, this field will be
cleared to ‘0’. The code 7 is unused and may be written by the CPU to check for update
Table 85.
0: no interrupt when WKUI is set.
1: interrupt generated when WKUI bit is set.
0: no interrupt when FOVR bit is set.
1: interrupt generated when FOVR bit is set.
