PARAMETERS

30       handle     The   access   handle   returned   from   csx_RequestIO(9F),
31                  csx_RequestWindow(9F), or csx_DupHandle(9F).
32
33
34       offset     The offset in bytes from the base of the mapped resource.

DESCRIPTION

38       These functions generate a read of various sizes from the mapped memory
39       or device register.
40
41
42       The csx_Get8(), csx_Get16(),  csx_Get32(),  and  csx_Get64()  functions
43       read  8 bits, 16 bits, 32 bits, and 64 bits of data, respectively, from
44       the device address represented by the handle, handle, at an  offset  in
45       bytes represented by the offset, offset.
46
47
48       Data  that  consists of more than one byte will automatically be trans‐
49       lated to maintain a consistent view between the  host  and  the  device
50       based  on the encoded information in the data access handle. The trans‐
51       lation may involve byte swapping if the host and the device have incom‐
52       patible endian characteristics.
53

RETURN VALUES

55       These functions return the value read from the mapped address.
56

CONTEXT

58       These functions may be called from user, kernel, or interrupt context.
