[AX5064I - 64 Channel Opto-isolated DI Board](v1.00)

Function:
   ax5064IInit

Description:
   Initialize the device.

   int ax5064IInit(int base_addr, int function);
   base_addr: I/O base address of the device.
   function: Function ID.

Remarks:
   This function should be called once before the device performming any data
   I/O functions. The function ID could be either of the constants listing below
   or any combinition of them:
      ID_FUNC_DI
      ID_FUNC_ALL

Return Values:
   This function will return an error code defined in the ERROR CODE LIST of
   AXDDR include file(axddr.h). Please be sure to check this returned value to
   determine whether the function call succeed or not. If there're no any error
   occured, the return value should be ERR_NOERR. Otherwise, the value will be
   the one defined in ERROR CODE LIST.


Function: ax5064ITerm

Description:
   Terminate the device driver.

   int ax5064ITerm(int base_addr);
   base_addr: I/O base address of the device.

Remarks:
   This function should be called once if the device will no longer performming
   any data I/O functions. Usually at the end of you data acquisition/control
   processes.

Return Values:
   This function will return an error code defined in the ERROR CODE LIST of

   occured, the return value should be ERR_NOERR. Otherwise, the value will be
   the one defined in ERROR CODE LIST.


Function:
   ax5064IGetDevAtbu

Description:
   Retrieve the device attribute.

   int ax5064IGetDevAtbu(LPDEVATBU lpDevAtbu);
   lpDevAtbu: Pointer to the DEVATBU struct, which stores the device attribute.

Return Values:
   This function will return an error code defined in the ERROR CODE LIST of
   AXDDR include file(axddr.h). Please be sure to check this returned value to
   determine whether the function call succeed or not. If there're no any error

   the one defined in ERROR CODE LIST.


Function:
   ax5064IDI

Description:
   Digital input function for a specified channel.

   int ax5064IDI(int base_addr, int chan, int* data);
   base_addr: I/O base address of the device.
   chan: Channel to perform DI function.
   data: Storage for digital input status.

Remarks:
   This function will retrieve the one and only specified channel for it's
   digital input status. The status value will stored in the third parameter,
   data, where '1' stands for 'HIGH' status, and '0' for 'LOW' one.

Return Values:
   This function will return an error code defined in the ERROR CODE LIST of

   Digital input function for a specified port(8-bit).

   int ax5064IDI_P(int base_addr, int port, int* data);
   base_addr: I/O base address of the device.
   port: Port number of DI channels. 1 port= 8 channel(bits).
   data: Storage for digital input status.

Remarks:
   This function will retrieve all the digital input status of channels in
   the same port at one time. 

Return Values:
   This function will return an error code defined in the ERROR CODE LIST of
   AXDDR include file(axddr.h). Please be sure to check this returned value to
