System Control
Register 16: Device Capabilities 1 (DC1), offset 0x010
This register is predefined by the part and can be used to verify features. The PWM, SARADC0,
MAXADCSPD, WDT, SWO, SWD, and JTAG bits mask the RCGC0, SCGC0, and DCGC0 registers.
Other bits are passed as 0. MAXADCSPD is clipped to the maximum value specified in DC1.

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.
PWM Module Present
When set, indicates that the PWM module 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.
ADC Module Present. When set, indicates that the ADC module is
present.
System Clock Divider. Minimum 4-bit divider value for system clock.
The reset value is hardware-dependent. See the RCC register for how
to change the system clock divisor using the SYSDIV bit.
Value Description
0x3 Specifies a 50-MHz CPU clock with a PLL divider of 4.

MPU Present. When set, indicates that the Cortex-M3 Memory Protection
Unit (MPU) module is present. See the "Cortex-M3 Peripherals" chapter
in the Stellaris Data Sheet for details on the MPU.
