Tiva^™ TM4C123AH6PM Microcontroller
Register 113: Device Capabilities 2 (DC2), offset 0x014
This register is predefined by the part and can be used to verify features. If any bit is clear in this
register, the module is not present. The corresponding bit in the RCGC1, SCGC1, DCGC1, and the
peripheral-specific RCGC, SCGC, and DCGC registers registers cannot be set.
Important: This register is provided for legacy software support only.
The Peripheral Present registers should be used to determine which modules are
implemented on this microcontroller. A read of DC2 correctly identifies if a legacy module
is present but software must use the Peripheral Present registers to determine if a
module is present that is not supported by the DCn registers.
Note that the Analog Comparator Peripheral Present (PPACMP) register identifies
whether the analog comparator module is present. The Analog Comparator Peripheral
Properties (ACMPPP) register indicates how many analog comparator blocks are
present 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.
EPI Module 0 Present
When set, indicates that EPI module 0 is present.
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.
I2S Module 0 Present
When set, indicates that I2S module 0 is present.
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 2 Present
When set, indicates that analog comparator 2 is present.
Analog Comparator 1 Present
When set, indicates that analog comparator 1 is present.
