EDMA_TPCC_ABCNT_n[15:0] ACNT represents the number of bytes within the 1st dimension of a transfer. ACNT is a 16-bit unsigned value with valid values between 0 and 65 535. Therefore, the maximum number of bytes in an array is 65 535 bytes (64K – 1 bytes). ACNT must be greater than or equal to 1 for a TR to be submitted to EDMA_TPTC. A transfer with ACNT equal to 0 is considered either a null or dummy transfer. A dummy or null transfer generates a completion code depending on the settings of the completion bit fields in EDMA_TPCC_OPT_n.
Refer to Section 16.2.4.3.5 Dummy Versus Null Transfer Comparison and Section 16.2.4.5.3 Dummy or Null Completion for details on dummy/null completion conditions.
