LAN1.ErrVector
9 1..Max. line of PL2
program lines
LAN1, Local area network 1
User's Manual 5.1 Inmotion Technologies AB
Doc. No.9032 0027 01 (B), Rev. 11.07.2001
RW
Address of the PL-code line to execute when a comm error
occurs.
LAN1.LastErr 10 1..7 R
The last error reported by the low level CAN protocol. This
member is most useful when the ErrVector is used.
0. No error
1. Stuff error
More than5 equal bits in a sequense have occured in a
part of a received message where this is not allowed.
2. Form Error
The fixed format part of a receivedframe has the wrong
format.
3. Acknowledgment Error
The message transmitted by this device was not
acknowledged by another node.
4. Bit 1 Error
During the transmission of a message, the 82527 wanted
to send a recessive level, (bit of logical value 1), but the
monitored CAN bus value dominant.
5. Bit 0 Error
During the transmission of a message, the 82527 wanted
to send a recessive level, (bit of logical value 0), but the
monitored CAN bus value was recessive. During busoff
recovery, this status is set each time a recessive bit is
received.
6. CRC Error
The CRC checksum was incorrect in the message
received. The CRC recevied for an incoming message
does not match with the CRC value calculated by this
device for the received data.
7. Unused.
LAN1.Handler 11 1..xx R
An interrupt handler for cascading interrupts from the LAN1
group. See cascading interrupts, Vector and Int. This member
is used when installing an interrupt cascade handler for the
LAN1 group. The Vector.Cascade member must be
initialized with this handler before interrupts can be generated
from the LAN1 group. Example:
; Setup the cascaded interrupt handler.
Vector.Cascade1 = LAN1.Handler Or
Int.SysMask, 256
; LAN1 can generate cascaded system
;interrupts
LAN1.ErrVector = @isrLANERR
or LAN1.Mask, 32768
; Allow errors to generate an interrupt
