pub struct XFERCOUNT_R(_);
Expand description
Field XFERCOUNT
reader - Total number of transfers to be performed, minus 1 encoded. The number of bytes transferred is: (XFERCOUNT + 1) x data width (as defined by the WIDTH field). The DMA controller uses this bit field during transfer to count down. Hence, it cannot be used by software to read back the size of the transfer, for instance, in an interrupt handler. 0x0 = a total of 1 transfer will be performed. 0x1 = a total of 2 transfers will be performed. 0x3FF = a total of 1,024 transfers will be performed.
Methods from Deref<Target = FieldReader<u16, u16>>
