CANSPIInitialize
Prototype
void CANSPIInitialize(char SJW, char BRP, char PHSEG1, char
PHSEG2, char PROPSEG, char CAN_CONFIG_FLAGS);
Description Initializes CANSPI. All pending transmissions are aborted. Sets all mask registers to 0
to allow all messages.
Filter registers are set according to flag value:
if (CAN_CONFIG_FLAGS & CAN_CONFIG_VALID_XTD_MSG != 0)
else if (config & CONFIG_VALID_STD_MSG != 0)
else
Parameters:
SJW
BRP
PHSEG1
PHSEG2
PROPSEG
CAN_CONFIG_FLAGS
145).
Requires CANSPI must be in Config mode; otherwise the function will be ignored.
Example
init = CAN_CONFIG_SAMPLE_THRICE
...
CANSPIInitialize(1, 1, 3, 3, 1, init);
