ATmega16M1/32M1/64M1
CANGSTA – CAN General Status Register
• Bit 0 – SWRES: Software Reset Request
This auto resettable bit only resets the CAN controller.
• Bit 7 – Res: Reserved
This bit is reserved and will always read as zero.
• Bit 6 – OVRG: Overload Frame Flag
This flag does not generate an interrupt.
• Bit 5 – Res: Reserved
This bit is reserved and will always read as zero.
• Bit 4 – TXBSY: Transmitter Busy
This flag does not generate an interrupt.
• Bit 3 – RXBSY: Receiver Busy
This flag does not generate an interrupt.
Initial Value
Read/Write
– 0 - standby mode: The on-going transmission (if exists) is normally terminated and the
– 1 - enable mode: The CAN channel enters in enable mode once 11 recessive bits
– 0 - no reset
– 1 - reset: this reset is “ORed” with the hardware reset
– 0 - no overload frame
– 1 - overload frame: set by hardware as long as the produced overload frame is sent
– 0 - transmitter not busy
– 1 - transmitter busy: set by hardware as long as a frame (data, remote, overload or
– 0 - receiver not busy
– 1 - receiver busy: set by hardware as long as a frame is received or monitored
Bit
CAN channel is frozen (the CONMOB bits of every MOb do not change). The transmitter
constantly provides a recessive level. In this mode, the receiver is not enabled but all the
registers and mailbox remain accessible from CPU. In this mode, the receiver is not
enabled but all the registers and mailbox remain accessible from CPU
has been read
error frame) or an ACK field is sent. Also set when an inter frame space is sent
Note:A standby mode applied during a reception may corrupt the on-going reception or set the
controller in a wrong state. The controller will restart correctly from this state if a software
reset (SWRES) is applied. If no reset is considered, a possible solution is to wait for a lake of
a receiver busy (RXBSY) before to enter in stand-by mode. The best solution is first to apply
an abort request command (ABRQ) and then wait for the lake of the receiver busy (RXBSY)
before to enter in stand-by mode. In any cases, this standby mode behavior has no effect on
the CAN bus integrity
