(1) Control function for the external general purpose outputs (GendoControlN)
<Name>
GendoControlN - Controls the external general purpose outputs (output1 to 8)
<Syntax>
DWORD GendoControlN(USINT usiOutput, USINT usiMask);
<Description of the functionality>
This function controls the external general purpose outputs (output1 to 8).
The parameters of this function are explained below.
usiOutput: Sets the output level to the general purpose outputs. Table 6-3 shows how
bits are allocated to each general purpose output. To set a general purpose
output to the low level, set the bit to “0”. To set the output to the high level,
set the bit to “1”.
usiMask: Specifies a general purpose output to be controlled. The bit allocation is the
same as usiOutput as shown in Table 6-3. If the parameter is to be controlled,
set the bit to “1”, Otherwise, set the bit to “0”.
