CAN0DATH: CAN Data Access Register High Byte.
The CAN0DAT Registers are used to read/write register values and data to and from the
CAN Registers pointed to with the index number in the CAN0ADR Register.
The CAN0ADR Register is used to point the [CAN0DATH:CAN0DATL] to a desired CAN
Register. The desired CAN Register’s index number is moved into CAN0ADR. The
CAN0DAT Register can then read/write to and from the CAN Register.
