Digi axis qualifier for axis channels 7 and 8

The digi register is used to check the status of the digital inputs in the APCI-8001. If the respective inputs are
active, this is displayed with the value 1 at the respective bit position.

rddigo, read digital outputs

See wrdigo in section [1.22.6]
This function is used to request the current status of one OPMF digital input and
various other logic signals. The axis number must be specified in the an parameter
(0, 1, ... MAXAXIS-1)
Note: Counting for the bit no. starts at 1.
function rddigib(an:integer; bitnr:integer):boolean;
int rddigib(int an, int bitnr);
Function rddigib(ByVal an As Long, ByVal bitnr As Long) As Long
The function returns the value 1 or TRUE, provided the corresponding bit no. input
is active.
See rddigi() section [1.2.2.2] and Note PHB rddigib() section [1.2.2.3]
