  58 .SH DESCRIPTION
  59 .sp
  60 .LP
  61 These functions generate a read of various sizes from the mapped memory or
  62 device register.
  63 .sp
  64 .LP
  65 The \fBcsx_Get8()\fR, \fBcsx_Get16()\fR, \fBcsx_Get32()\fR, and
  66 \fBcsx_Get64()\fR functions read 8 bits, 16 bits, 32 bits, and 64 bits of data,
  67 respectively, from the device address represented by the handle, \fIhandle\fR,
  68 at an offset in bytes represented by the offset, \fIoffset\fR.
  69 .sp
  70 .LP
  71 Data that consists of more than one byte will automatically be translated to
  72 maintain a consistent view between the host and the device based on the encoded
  73 information in the data access handle. The translation may involve byte
  74 swapping if the host and the device have incompatible endian characteristics.
  75 .SH RETURN VALUES
  76 .sp
  77 .LP
  78 These functions return the value read from the mapped address.
  79 .SH CONTEXT
  80 .sp
  81 .LP
  82 These functions may be called from user, kernel, or interrupt context.
