.SH DESCRIPTION
.sp
.LP
These functions generate multiple reads of various sizes from the mapped memory
or device register.
.sp
.LP
The \fBcsx_RepGet8()\fR, \fBcsx_RepGet16()\fR, \fBcsx_RepGet32()\fR, and
\fBcsx_RepGet64()\fR functions generate \fIrepcount\fR reads of 8 bits, 16
bits, 32 bits, and 64 bits of data, respectively, from the device address
represented by the handle, \fIhandle\fR, at an offset in bytes represented by
the offset, \fIoffset\fR. The data read is stored consecutively into the buffer
pointed to by the host address pointer, \fIhostaddr\fR.
.sp
.LP
Data that consists of more than one byte will automatically be translated to
maintain a consistent view between the host and the device based on the encoded
information in the data access handle. The translation may involve byte
swapping if the host and the device have incompatible endian characteristics.
.sp
.LP
When the \fIflags\fR argument is set to \fBCS_DEV_AUTOINCR\fR, these functions
increment the  device offset, \fIoffset\fR, after each datum read operation.
However, when the \fIflags\fR argument is set to \fBCS_DEV_NO_AUTOINCR\fR, the
same device offset will be used for every datum access. For example, this flag
may be useful when reading from a data register.
.SH CONTEXT
.sp
.LP
These functions may be called from user, kernel, or interrupt context.
