• char PCI1389S02_StartCounter (unsigned char Card, unsigned char Flags);

This function will start the counters. The counters can be started separatly or
together if ORed. See file PCI1389S02.H.

• char PCI1389S02_StopCounter (unsigned char Card, unsigned char Flags);

This function will stop the counter. As described in StartCounter, the counters
can be stopped separatly or together.

• char

PCI1389S02_GetStatus

(unsigned

char

Card,

struct

_PCI1389S02_STAT *Status);
This function reads the state of all 3 counters. The meaning of the bits can be
seen in the file PCI1389S02.H.

• char PCI1389S02_GetCNT1Values (unsigned char Card, long (*buffer)[], un-

signed long buffersize, unsigned long *n);
This function will read counter-values out of the fifo. If no values are saved, n
will be set to 0. If values are read, n will show the amount of values (not bytes!).

• char PCI1389S02_GetCNT2Values (unsigned char Card, long (*buffer)[], un-

signed long buffersize, unsigned long *n);
See function GetCNT1Values, but used for counter 2.

• char PCI1389S02_LatchCounter (unsigned char Card, unsigned char Flags);

This function will latch the counters if softwaretrigger is enabled. The counters
can be latched separately or together.

• char  PCI1389S02_SetPorts

(unsigned char Card, unsigned char Flags);

This function will set the digital outputs (bit 3 to 0).

• char PCI1389S02_GetPorts

(unsigned char Card, unsigned char *Flags);

This function will read the digital inputs (bit 7 to 4) and will read back the digital
outputs (bit 3 to 0).
