CRSTSTS Flag (Channel Reset Status Flag)
This flag becomes 1 when the CAN module has transitioned to channel reset mode, and becomes 0 when the CAN
module has transitioned to channel communication mode or channel halt mode. This flag remains 1 even if the CAN
module transitions from channel reset mode to channel stop mode.
CHLTSTS Flag (Channel Halt Status Flag)
This flag becomes 1 when the CAN module has transitioned to channel halt mode, and becomes 0 when the CAN module
has exited channel halt mode.
CSLPSTS Flag (Channel Stop Status Flag)
This flag becomes 1 when the CAN module has transitioned to channel stop mode, and becomes 0 when the CAN
module has returned from channel stop mode.
EPSTS Flag (Error Passive Status Flag)
This flag becomes 1 when the CAN module has entered the error passive state (128 STSH.TEC[7:0] value 255 or
128 STSH.REC[7:0] value), and becomes 0 when the CAN module has exited the error passive state or has entered
channel reset mode.
BOSTS Flag (Bus Off Status Flag)
This flag becomes 1 when the CAN module has entered the bus off state (STSH.TEC[7:0] value > 255), and becomes 0
