Bit 2 — Message Transmission in progress Flag (GSR2): Flag that indicates to the CPU if the

RCAN-TL1 is in Bus Off or transmitting a message or an error/overload flag due to error detected

during transmission. The timing to set TXACK is different from the time to clear GSR2. TXACK

is set at the 7

messages ready to be transmitted. It is also set by arbitration lost, bus idle, reception, reset or halt

Bit 1—Transmit/Receive Warning Flag (GSR1): Flag that indicates an error warning.

Note: REC is incremented during Bus Off to count the recurrences of 11 recessive bits as

Bit 0—Bus Off Flag (GSR0): Flag that indicates that RCAN-TL1 is in the bus off state.

Note: Only the lower 8 bits of TEC are accessible from the user interface. The 9

RCAN-TL1 is in Bus Off or a transmission is in progress

[Setting condition]

Not in Bus Off and no transmission in progress (Initial value)

[Reset condition] When (TEC < 96 and REC < 96) or Bus Off (Initial value)

[Setting condition] When 96 ≤ TEC < 256 or 96 ≤ REC < 256

[Reset condition]

Recovery from bus off state or after a HW or SW reset (Initial value)

[Setting condition] When TEC ≥ 256 (bus off state)
