Tiva™ TM4C1236H6PM Microcontroller
Register 30: Universal Asynchronous Receiver/Transmitter Peripheral Present
(PPUART), offset 0x318
The PPUART register provides software information regarding the UART modules.
Important: This register should be used to determine which UART modules are implemented on
this microcontroller. However, to support legacy software, the DC2 register is available.
A read of the DC2 register correctly identifies if a legacy UART module is present.
Software must use this register to determine if a module that is not supported by the
DC2 register 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.
