NAME

     csx_RepGet8, csx_RepGet16, csx_RepGet32, csx_RepGet64 - read
     repetitively from the device register

SYNOPSIS

     #include <sys/pccard.h>

     void  csx_RepGet8(acc_handle_t  handle,  uint8_t  *hostaddr,
     uint32_t offset, uint32_t repcount, uint32_t flags);

     void csx_RepGet16(acc_handle_t handle,  uint16_t  *hostaddr,
     uint32_t offset, uint32_t repcount, uint32_t flags);

     void csx_RepGet32(acc_handle_t handle,  uint32_t  *hostaddr,
     uint32_t offset, uint32_t repcount, uint32_t flags);

     void csx_RepGet64(acc_handle_t handle,  uint64_t  *hostaddr,
     uint32_t offset, uint32_t repcount, uint32_t flags);

PARAMETERS

     handle
           The access  handle  returned  from  csx_RequestIO(9F),
           csx_RequestWindow(9F), or csx_DupHandle(9F).

     hostaddr
           Source host address.

     offset
           The offset in  bytes  from  the  base  of  the  mapped
           resource.

     repcount
           Number of data accesses to perform.

     flags Device address flags.

DESCRIPTION

     These functions generate multiple  reads  of  various  sizes
     from the mapped memory or device register.

     The  csx_RepGet8(),  csx_RepGet16(),   csx_RepGet32(),   and
     csx_RepGet64()  functions generate repcount reads of 8 bits,
     16 bits, 32 bits, and 64 bits of  data,  respectively,  from
     the  device address represented by the handle, handle, at an
     offset in bytes represented by the offset, offset. The  data
     read  is  stored consecutively into the buffer pointed to by
     the host address pointer, hostaddr.

     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  charac-
     teristics.

     When the flags argument is  set  to  CS_DEV_AUTOINCR,  these
     functions  increment  the  device offset, offset, after each
     datum read operation. However, when the  flags  argument  is
     set  to  CS_DEV_NO_AUTOINCR,  the same device offset will be
     used for every datum access. For example, this flag  may  be
     useful when reading from a data register.

CONTEXT

     These functions may be called from user, kernel,  or  inter-
     rupt context.
