This register allows the you to specify the
maximum limit of deltasum. In loop control mode, the ACR internally adjusts the value of N or
Maud to vary the output frequency. This register specifies the maximum limit of this
variation. For example, if N=6000 and this register is programmed as 200, then the ACR
internally varies the value of N to a maximum value of 6200 and a minimum value of 5800.

mode. |
