ADC2_DMA_RMP[1] on STM32F334 (Rm0364)

Hello,

as there is no DMA2 on the STM32F334, the SYSCFG->CFGR3 Bit 9 ADC2_DMA_RMP[1] has a misleading description. Following the description, is has to be kept set. 10.1.8 SYSCFG configuration register 3 (SYSCFG_CFGR3) is also missing Address offset and System reset value.

Hello

Bonnes.Uwe

,

You are right, the description will be changed to:

Bit 9 ADC2_DMA_RMP[1]: ADC2 DMA controller remapping bit

0: Reserved

1: ADC2 mapped on DMA1

We will add the

missing Address offset and System reset value:

  • Address offset:

    0x50

  • System reset value:

    0x200

This is

rasied internally for update in the coming release of the reference manual RM0

With Regards,

Imen.
