TM4C123BE6PZ Datasheet, PDF (295/1299 Pages) Texas Instruments – This data sheet provides reference information for the TM4C123BE6PZ microcontroller, describing

Tiva^™ TM4C123BE6PZ Microcontroller _{(identical to LM4F212E5QC)}
Register 37: Analog Comparator Peripheral Present (PPACMP), offset 0x33C
The PPACMP register provides software information regarding the analog comparator module.
Important: This register should be used to determine if the analog comparator module is
implemented on this microcontroller. However, to support legacy software, the DC2
register is available. A read of the DC2 register correctly identifies if the analog
comparator module is present.
Note that the Analog Comparator Peripheral Properties (ACMPPP) register indicates
how many analog comparator blocks are included in the module.

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.
Analog Comparator Module Present
Value Description
1 Analog comparator module is present.
0 Analog comparator module is not present.
