7647G–AVR–09/11
CAN General Control Register - CANGCON
• Bit 7 – ABRQ: Abort Request
This is not an auto resettable bit.
• Bit 6 – OVRQ: Overload Frame Request
This is not an auto resettable bit.
The overload frame can be traced observing OVFG in CANGSTA register (c.f.
page
• Bit 5 – TTC: Time Trigger Communication
• Bit 4 – SYNTTC: Synchronization of TTC
This bit is only used in TTC mode.
• Bit 3 – LISTEN: Listening Mode
• Bit 2 – TEST: Test Mode
Note:
• Bit 1 – ENA/STB: Enable / Standby Mode
Because this bit is a command and is not immediately effective, the ENFG bit in CANGSTA
register gives the true state of the chosen mode.
Initial Value

Bit
– 0 - no request.

– 0 - no TTC.
– 1 - TTC mode.
– 0 - the TTC timer is caught on SOF.
– 1 - the TTC timer is caught on the last bit of the EOF.
– 0 - no listening mode.
– 1 - listening mode.
– 0 - no test mode
– 1 - test mode: intend for factory testing and not for customer use.
communications are immediately disabled and the on-going one will be normally
terminated, setting the appropriate status flags.
Note that CANCDMOB register remain unchanged.
CAN may malfunction if this bit is set.
