Description
PWM Module 0 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 1 Present
When set, indicates that ADC module 1 is present.
ADC Module 0 Present
When set, indicates that ADC module 0 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
0x1 Reserved
0x2 Specifies an 80-MHz CPU clock with a PLL divider of 2.5.
0x3 Specifies a 50-MHz CPU clock with a PLL divider of 4.
0x4 Specifies a 40-MHz CPU clock with a PLL divider of 5.
0x7 Specifies a 25-MHz clock with a PLL divider of 8.
0x9 Specifies a 20-MHz clock with a PLL divider of 10.
0x3
Max ADC1 Speed
This field indicates the maximum rate at which the ADC samples data.
Value Description
0x3 1M samples/second
0x2 500K samples/second
0x1 250K samples/second
0x0 125K samples/second
0x3
Max ADC0 Speed
This field indicates the maximum rate at which the ADC samples data.
Value Description
0x3 1M samples/second
0x2 500K samples/second
0x1 250K samples/second
0x0 125K samples/second
0x1
MPU Present
When set, indicates that the Cortex-M4F Memory Protection Unit (MPU)
module is present. See the "Cortex-M4F Peripherals" chapter for details
on the MPU.
