Syscfg External Interrupt Configuration Register 1; (Syscfg_Exticr1) - STMicroelectronics RM0365 Reference Manual

RM0365
Bit 11 TIM16_DMA_RMP: TIM16 DMA request remapping bit
This bit is set and cleared by software. It controls the remapping of TIM16 DMA request.
Bits 10:9 Reserved, must be kept at reset value.
Bit 8 ADC2_DMA_RMP: ADC2 DMA remapping bit (STM32F302xB/C/D/E devices only)
This bit is set and cleared by software. It controls the remapping of ADC24 DMA requests.
Bit 7 DAC1_TRIG_RMP: DAC trigger remap (when TSEL = 001) (STM32F302xB/C/D/E devices
only)
This bit is set and cleared by software. It controls the mapping of the DAC trigger source.
Bit 6 TIM1_ITR3_RMP: Timer 1 ITR3 selection
This bit is set and cleared by software. It controls the mapping of TIM1 ITR3.
Bits 5:3 Reserved, must be kept at reset value.
Bits 2:0 MEM_MODE: Memory mapping selection bits
This bit is set and cleared by software. It controls the memory internal mapping at address
0x0000 0000. After reset these bits take on the memory mapping selected by BOOT0 pin and
BOOT1 option bit.
