What is the register behavior of "rw_wt"?

I'm trying to understand the register behavior of rw_wt.In the RM0090, Ethernet DMA transmit poll demand register (ETH_DMATPDR) has a register. this register declared as "rw_wt". But I don't know how rw_wt work.Could you please clarify the register b...

STM32F072RB DP and DM Can't connect to computer

USB Type C HOST Charging? How can I achieve this on hardware level without any programming.

I have a usb HUB which is externally powered now i want to charge my HOST(Smart phone) through my HUB which seems not possible without using an PD controller.I stumbled upon STUSB4761 which seems like a perfect choice for me but i am not sure about i...

I am working with STM32F407 to write a text file to Pendrive (USB Host). But i am getting FD_DISC_ERR. When I debugged more i understood that this is due to HOST_DEV_WAIT_FOR_ATTACHMENT issue. Can anyone help why this is happening?

Multiple EXTI GPIO EVENTS-STM32G0 I would to know is someone could provide some tips on using GPIOs as External Events (EXTI) sources on STM2G0 HAL. Any information is welcome BR Gilberto

I have an STM32H743. I am trying to configure a Layer 4 inverse filter on destination port . My intention is to allow all broadcast traffic except for one that has a particular destination port.

I am configuring the following control registers.  heth->Instance->MACCR |= ETH_MACCR_IPC; // INVERSE MATCHING heth->Instance->MACPFR |= ETH_MACPFR_IPFE; heth->Instance->MACL3L4C0R |= 1<<21;//ETH_MACL3L4C0R_L4DPIM0; heth->Instance->MACL3L4C0R |= 1<<2...

How to get the DFSDM to trigger the HAL_DFSDM_FilterAwdCallback

I'm using a STM32L475. I have DFSDM data coming in. I'm using the AWD and have set high and low thresholds to trigger an interrupt. I cannot get the interrupt to occur. The DFSDM_FLT1AWSR flags get set. The DFSDM_FLT1ISR->AWDF flag also gets set. Any...

Accuracy of USB clock on STM32L496ZGT when using MSI (without LSE/non-PLL mode) vs HSI48 with CRS

MSI (without LSE/non-PLL mode) vs HSI48 with CRSWhich is the more accurate clock to use for STM32L496ZGT in USB slave mode and what are they relative accuracies?

STM32L4P5CG and bootloader programming appear to have L1 mem protection set now

I have an application running on an STM32L4P5. Initially, I programmed and debugged with J-Link on the micro 9-pin SWDIO connector. All worked great, I could use J-Mem to peer into sram or flash in real time. Then I built a bootloader over USB, using...
