·For transfer modes 0 to D, set this register to the number of ATC activations. The register decrements by 1 after every ATC1 activation. When the count reaches x'00', an ATC1 interrupt occurs and the transfer ends.

·For transfer modes E and F, set this register to number of burst transfers. The register decrements by 1 every time one byte

is transfered. When the count reaches x'00', an ATC1 interrupt occurs and the transfer ends.
