///Field `BNDT` reader - block number of data bytes to transfer from the source Block size transferred from the source. When the channel is enabled, this field becomes read-only and is decremented, indicating the remaining number of data items in the current source block to be transferred. BNDT\[15:0\] is programmed in number of bytes, maximum source block size is 64 Kbytes -1. Once the last data transfer is completed (BNDT\[15:0\] = 0): - if GPDMA_CxLLR.UB1 = 1, this field is updated by the LLI in the memory. - if GPDMA_CxLLR.UB1 = 0 and if there is at least one non null Uxx update bit, this field is internally restored to the programmed value. - if all GPDMA_CxLLR.Uxx = 0 and if GPDMA_CxLLR.LA\[15:0\] = 0, this field is internally restored to the programmed value (infinite/continuous last LLI). - if GPDMA_CxLLR = 0, this field is kept as zero following the last LLI data transfer. Note: A non-null source block size must be a multiple of the source data width (BNDT\[2:0\] versus GPDMA_CxTR1.SDW_LOG2\[1:0\]). Else a user setting error is reported and no transfer is issued. Note: When configured in packing mode (GPDMA_CxTR1.PAM\[1\] = 1 and destination data width different from source data width), a non-null source block size must be a multiple of the destination data width (BNDT\[2:0\] versus GPDMA_CxTR1.DDW_LOG2\[1:0\]).
