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