The TEC register reflects the current value of the CAN Transmit Error Counter. This register can be written by SPI command for test
purposes.
Bit Name
7-0 TEC7:0
The REC register reflects the current value of the CAN Receive Error Counter. This register can be written by SPI command for test
purposes.
Bit Name

register. ERRP also set in STATF register. This may be used to generate a hardware interrupt if
ERRPIE bit is set in STATFE register.
TEC > 255: Bus-off status. Bus-off flags, BUSOFF, set in ERR and STATF registers. The
latter may be used to generate a hardware interrupt if BUSOFFIE bit is set in STATFE register.
The HI-3110 will, after entering bus-off state, automatically recover to error active status
without host intervention if the BOR bit is set in control register CTRL0 and 128 x 11
consecutive recessive bits are detected on the bus. If the BOR bit is not set, bus-off recovery is
managed by the host.
