(2) Get function for the external general purpose inputs (GetGendiN)
<Name>
GetGendiN - Acquires the status of the external general purpose inputs (general-
purpose input1 to 7)
<Syntax>
DWORD GetGendiN(POINTER TO USINT pusiInput);
<Description of the functionality>
This function acquires the status of the external general purpose inputs.
The parameters of this function are explained below.
pusiInput: The input state of external general purpose input is stored. Table 6-5 shows
how bits are allocated to each general purpose input. If the input level of a
general purpose input is low, “0” is stored to the corresponding bit, and “1”
otherwise.
