Register 15: Device Capabilities 2 (DC2), offset 0x014
This register provides a list of features available in the system. The Stellaris family uses this register
format to indicate the availability of the following family features in the specific device: Analog
Comparators, General-Purpose Timers, I2Cs, QEIs, SSIs, and UARTs. The format of this register
is consistent with the RCGC1, SCGC1, and DCGC1 clock control registers and the SRCR1 software
reset control register.

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 2 Present
When set, indicates that analog comparator 2 is present.
Analog Comparator 1 Present
When set, indicates that analog comparator 1 is present.
Analog Comparator 0 Present
When set, indicates that analog comparator 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.
Timer 2 Present
When set, indicates that General-Purpose Timer module 2 is present.
Timer 1 Present
When set, indicates that General-Purpose Timer module 1 is present.
Timer 0 Present
When set, indicates that General-Purpose Timer 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.
I2C Module 0 Present
When set, indicates that I2C module 0 is present.
