Section 19 Controller Area Network (RCAN-TL1)
Bit 4 - Receive Error Counter Warning Interrupt Flag (IRR4): This bit becomes set if the
receive error counter (REC) reaches a value greater than 95 when RCAN-TL1 is not in the Bus
Off status. The interrupt is reset by writing a ‘1’ to this bit position, writing ‘0’ has no effect.
Bit 3 - Transmit Error Counter Warning Interrupt Flag (IRR3): This bit becomes set if the
transmit error counter (TEC) reaches a value greater than 95. The interrupt is reset by writing a ‘1’
to this bit position, writing ‘0’ has no effect.
Bit 2 - Remote Frame Receive Interrupt Flag (IRR2): Flag indicating that a remote frame has
been received in a mailbox. This bit is set if at least one receive mailbox, with related MBIMR not
set, contains a remote frame transmission request. This bit is automatically cleared when all bits in
the Remote Frame Receive Pending Register (RFPR), are cleared. It is also cleared by writing a
‘1’ to all the correspondent bit position in MBIMR. Writing to this bit has no effect.
Bit 1 – Data Frame Received Interrupt Flag (IRR1): IRR1 indicates that there are pending Data
Frames received. If this bit is set at least one receive mailbox contains a pending message. This bit
is cleared when all bits in the Data Frame Receive Pending Register (RXPR) are cleared, i.e. there
is no pending message in any receiving mailbox. It is in effect a logical OR of the RXPR flags
from each configured receive mailbox with related MBIMR not set. It is also cleared by writing a
‘1’ to all the correspondent bit position in MBIMR. Writing to this bit has no effect.
