.SH DESCRIPTION
.sp
.LP
The \fBddi_fm_dma_err_clear()\fR and \fBddi_fm_acc_err_clear()\fR functions clear the error status of a \fBDMA\fR or access handle respectively.
.sp
.LP
Once cleared, the driver is again able to access the mapped registers or memory using programmed \fBI/O\fR through the handle.
