Description

The SDMMC_DLENR register contains the number of data bytes to be transferred. The value is loaded into the data counter when data transfer starts.

Fields

DATALENGTH

Data length value This register can only be written by firmware when DPSM is inactive (DPSMACT = 0). Number of data bytes to be transferred. When DDR = 1 DATALENGTH is truncated to a multiple of 2. (The last odd byte is not transfered) When DATALENGTH = 0 no data will be transfered, when requested by a CPSMEN and CMDTRANS = 1 also no command will be transfered. DTEN and CPSMEN are cleared to 0.
