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 0x09
specifies a 20-MHz CPU clock with a PLL divider of 10.
See the RCC register (page 79) 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.
