17.3.11 Accumulation of Several Measurements.

The ITC module can repeat the CVD measurement for each list record (CVDANx pin) several times and accumulate the result before storing it in ITCRESx registers. The ACCEN bit in the ITCLSxSEQ register must be always set to have the accumulation feature available.

The ITC will run CVD multiple times for a record with an assigned CVDANx pin as it is defined in ACCCNT[3:0] bits of the ITCLSxSEQ register.

The number of the accumulated CVD measurements is 2^ACCCNT[3:0] (ACCCNT[3:0] = 1 means accumulation of 2 results, ACCCNT[3:0] = 2 means accumulation of 4 results and so on).

When ACCCNT[3:0] bits are zero, the CVD measurement is performed just once (without accumulations).

When all accumulations are done, the ACCDONE bit is set in the ITCRECx register. ACCDONE bits in the records registers are cleared when the corresponding ITCRESx register is read.
