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
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.

int ax5032IODI_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 channels(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
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
