Tiva^™ TM4C123GH6PZ Microcontroller
Register 27: 16/32-Bit General-Purpose Timer Peripheral Present (PPTIMER),
offset 0x304
The PPTIMER register provides software information regarding the 16/32-bit general-purpose timer
modules.
Important: This register should be used to determine which timers 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 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.
