dmagrp_interrupt_enable

         <b> Register 7 (Interrupt Enable Register) </b>

The Interrupt Enable register enables the interrupts reported by Register 5 (Status Register). Setting a bit to 1'b1 enables a corresponding interrupt. After a hardware or software reset, all interrupts are disabled.
