System configuration controller (SYSCFG)

Bits 31:2 Reserved, must be kept at reset value.

SYSCFG peripheral mode configuration register (SYSCFG_PMC)

Address offset: 0x04

Reset value: 0x0000 0000

Bits 31:17 Reserved, must be kept at reset value.

Bits 15:0 Reserved, must be kept at reset value.

Bits 1:0 MEM_MODE: Memory mapping selection

Set and cleared by software. This bit controls the memory internal mapping at

address 0x0000 0000. After reset these bits take the value selected by the Boot

00: Main Flash memory mapped at 0x0000 0000

01: System Flash memory mapped at 0x0000 0000

10: reserved

11: Embedded SRAM mapped at 0x0000 0000

Note: Refer to

address 0x0000 0000.

Bit 16 ADC1DC2:

0: No effect.

1: Refer to AN4073 on how to use this bit

Note: These bits can be set only if the following conditions are met:

- ADC clock higher or equal to 30 MHz.

- Only one ADC1DC2 bit must be selected if ADC conversions do not start

at the same time and the sampling times differ.

- These bits must not be set when the ADCDC1 bit is set in PWR_CR
