TM4C1233E6PM Datasheet, PDF (294/1214 Pages) Texas Instruments – Tiva Microcontroller

System Control
Register 35: Controller Area Network Peripheral Present (PPCAN), offset 0x334
The PPCAN register provides software information regarding the CAN modules.
Important: This register should be used to determine which CAN modules are implemented on
this microcontroller. However, to support legacy software, the DC1 register is available.
A read of the DC1 register correctly identifies if a legacy CAN module is present.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
