Flag excessively high transmit or receive error counts on TouCAN modules
Target Support Package FM5/ MPC555 Driver Library/ CAN 2.0B Controller Module

The TouCAN Warnings block has two logical outputs, RX and TX. If the transmit error counter is over 95, then the TX output goes high. If the receive error counter is over 95, then the RX output goes high.
Use this block, in conjunction with a TouCAN Error Count block, to monitor error conditions on a selected TouCAN module.

Select TouCAN module A, B or C. Note that the MPC555 only has modules A and B. MPC56x (561-6) also have module C. An error will be thrown if you select C and your target processor does not support this.
Sample time of the block.
