Register 15: Device Capabilities 1 (DC1), offset 0x010
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: PWM, ADC,
Watchdog timer, and debug capabilities. This register also indicates the maximum clock frequency
and maximum ADC sample rate. The format of this register is consistent with the RCGC0, SCGC0,
and DCGC0 clock control registers and the SRCR0 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.
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.
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.
Max ADC Speed
Indicates the maximum rate at which the ADC samples data.
MPU Present
When set, indicates that the Cortex-M3 Memory Protection Unit (MPU)
module is present. See the ARM Cortex-M3 Technical Reference Manual
for details on the MPU.
