Description
Reserved bits return an indeterminate value, and should
never be changed.
A 1 in this bit indicates the presence of the PWM module.
Reserved bits return an indeterminate value, and should
never be changed.
A 1 in this bit indicates the presence of the ADC module.
The reset value is hardware-dependent. A value of 0x7
specifies a 25-MHz clock with a PLL divider of 8. See the
RCC register (page 86) for how to change the system clock
divisor using the SYSDIV bit.
This field indicates the maximum rate at which the ADC
samples data. A value of 0x1 indicates 250K samples per
second.
This bit indicates whether the Memory Protection Unit
(MPU) in the Cortex-M3 is available. A 0 in this bit indicates
the MPU is not available; a 1 indicates the MPU is
available.
See the ARM® Cortex™-M3 Technical Reference Manual
for details on the MPU.
Reserved bits return an indeterminate value, and should
never be changed.
This bit specifies the presence of an internal temperature
sensor.
A 1 in this bit indicates the presence of an implemented
PLL in the device.
A 1 in this bit indicates a watchdog timer on the device.
