Register 18: Device Capabilities 4 (DC4), offset 0x01C
This register provides a list of features available in the system. The Stellaris family uses this register
format to indicate the availability of GPIOs in the specific device. The format of this register is
consistent with the RCGC2, SCGC2, and DCGC2 clock control registers and the SRCR2 software
reset control register.
