ADVANTAGES
The user interrupt routine is called directly from the interrupt routine
of the driver (ring 0). The time between interrupt and user interrupt
routine is reduced.
A debug of the user interrupt routine is not possible.
The user interrupt routine cannot call the Windows API functions.
LIMITS
The user interrupt routine cannot call the functions, which have
access to the shared variable. However, the user can use a shared
memory.
The user interrupt routine can only call the functions of the xPCI-
1710 device driver, which have the following extension:
"i_APCI1710_KRNL_XXX"
This mode can not be used under Visual Basic.
ASYNCHRONOUS
MODE
A debug of the user interrupt routine is possible.
ADVANTAGES
The user interrupt routine can call the API functions.
The user interrupt routine can call the functions, which have access to
the shared variable.
The user interrupt routine can call all functions of the xPCI-1710 device
driver. Syntax: "i_APCI1710_XXX"
LIMITS
The code of the user interrupt routine is called from the Interrupt Thread
of the driver (ring 3). The time between interrupt and user interrupt
routine is longer.
