pulRegister is an unsigned long pointer to the first register of the CAN controller’s data registers. For example in order to use the IF1 register set on CAN controller 1 the value would
be: (CAN0_BASE + CAN_O_IF1DA1).
iSize is the number of bytes to copy from the CAN controller.
Description:
This function takes the steps necessary to copy data to a contiguous buffer in memory from the
non-contiguous data registers used by the CAN controller. This function is rarely used outside
of the CANMessageGet() function.
Returns:
None.
4.2.5.17 CANReadReg
Reads a CAN controller register.
Prototype:
unsigned long
CANReadReg(unsigned long ulRegAddress)
Parameters:
ulRegAddress is the full address of the CAN register to be read.
Description:
This function takes care of the synchronization necessary to read from a CAN controller register.
Note:
This function takes care of delay required to access CAN registers. This delay is required when
accessing CAN registers directly.
Returns:
The current value of the register that was requested by ulRegAddress.
4.2.5.18 CANRetryGet
Returns the current setting for auto-retransmission.
Prototype:
tBoolean
CANRetryGet(unsigned long ulBase)
Parameters:
ulBase is the base address of the CAN controller.
Description:
Reads the current setting of the auto-retransmission setting in the CAN controller and returns
it to the caller.
Returns:
true if automatic retransmission is enabled, false otherwise.
