6.12.4 _9116_GP0_Set_GATE_SRC
@ Description
This function is used to select the gate source of GPTC. When internal
gate source is selected, you can use function _9116_GP0_EN to
enable/disable the counting.
@ Syntax
C/C++ (DOS)
int _9116_GP0_Set_GATE_SRC( I16 card_number, U8 gate_src )
@ Argument
card_number: the card number of cPCI-9116 to be initialized,
totally 4 cards can be initialized, the valid card
numbers are CARD_1, CARD_2, CARD_3,
CARD_4.
gate_src : 0: internal gate source
1: external clock source from pin97 of J1
@ Return Code
ERR_NoError
ERR_BoardNoInit
6.12.5 _9116_GP0_Set_UPDOWN_SRC
@ Description
This function is used to select the up/down control source of GPTC.
When internal source is selected, you can use function
_9116_GP0_Set_UPDOWN() to select up/down counter operation.
@ Syntax
