Description

DMA control register

Fields

DBA

DMA base address This 5-bit vector defines the base-address for DMA transfers (when read/write access are done through the TIMx_DMAR address). DBA is defined as an offset starting from the address of the TIMx_CR1 register. Example: … Example: Let us consider the following transfer: DBL = 7 transfers & DBA = TIMx_CR1. In this case the transfer is done to/from 7 registers starting from the TIMx_CR1 address.

0 (B_0x0): TIMx_CR1

1 (B_0x1): TIMx_CR2

2 (B_0x2): TIMx_SMCR

DBL

DMA burst length This 5-bit vector defines the number of DMA transfers (the timer recognizes a burst transfer when a read or a write access is done to the TIMx_DMAR address). …

0 (B_0x0): 1 transfer,

1 (B_0x1): 2 transfers,

2 (B_0x2): 3 transfers,

17 (B_0x11): 18 transfers.
