Test Register
| Res | Reserved There are reserved bits. These bits are always read as ‘0’ and must always be written with ‘0’. |
| Basic | Basic Mode 1= IF1 Registers used as Tx Buffer, IF2 Registers used as Rx Buffer. 0 = Basic Mode disabled. |
| Silent | Silent Mode 1 = The module is in Silent Mode. 0 = Normal operation. |
| LBack | Loop Back Mode 1 = Loop Back Mode is enabled. 0 = Loop Back Mode is disabled. |
| Tx | Tx[1:0]: Control of CAN_TX pin 00 = Reset value, CAN_TX is controlled by the CAN Core 01 = Sample Point can be monitored at CAN_TX pin 10 = CAN_TX pin drives a dominant (‘0’) value. 11 = CAN_TX pin drives a recessive (‘1’) value. |
| Rx | Monitors the actual value of CAN_RX Pin (Read Only) 1 = The CAN bus is recessive (CAN_RX = ‘1’). 0 = The CAN bus is dominant (CAN_RX = ‘0’). |
