244/324
Bit 3 = reserved. Forced to 0 by hardware.
Bit 2 = BOFF Bus-Off Flag
Read
This bit is set by hardware when it enters the bus-off state. The bus-off state is entered on
TECR overrun, TEC greater than 255, refer to
Bit 1 = EPVF Error Passive Flag
Read
This bit is set by hardware when the error passive limit has been reached (receive error
counter or transmit error counter greater than 127).
Bit 1 = EWGF Error Warning Flag
Read
This bit is set by hardware when the warning limit has been reached. Receive error counter
or transmit error counter greater than 96.
CAN error interrupt enable register (CEIER)
Read/ write
Reset value: 0000 0000 (00h)
All bits of this register are set and clear by software.
Bit 7 = ERRIE Error Interrupt Enable
Bits 6:5 = reserved. Forced to 0 by hardware.
Bit 4 = LECIE Last Error Code Interrupt Enable
Bit 3 = reserved. Forced to 0 by hardware.
Bit 2 = BOFIE Bus-Off Interrupt Enable
Bit 1 = EPVIE Error Passive Interrupt Enable
Bit 0 = EWGIE Error Warning Interrupt Enable
ERRIE
0: no interrupt will be generated when an error condition is pending in the CESR.
1: an interrupt will be generation when an error condition is pending in the CESR.
0: ERRI bit will not be set when the error code in LEC[2:0] is set by hardware on error
detection.
1: ERRI bit will be set when the error code in LEC[2:0] is set by hardware on error
detection.
0: ERRI bit will not be set when BOFF is set.
1: ERRI bit will be set when BOFF is set.
0: ERRI bit will not be set when EPVF is set.
1: ERRI bit will be set when EPVF is set.
0: ERRI bit will not be set when EWGF is set.
1: ERRI bit will be set when EWGF is set.
