6.4.2.8 Disable an Individual Interrupt Source — TCdisableInterruptChip

Disables an interrupt source at the second level if it is a valid interrupt source for the card. If

the interrupt source is active, it will be deactivated.

SUPPORTED IN VERSION 4.40 UPWARDS

In versions of the DLL from version 4.40 onwards, all valid interrupt sources are initially

enabled at the second level.

i = TCdisableInterruptChip (h, Chip)

where h short: board handle as issued by the

registerBoardEx function.

Chip short: interrupt source as used in the user

interrupt set-up functions. For historic reasons,

this corresponds to a bit position in the

interrupt enable (IE) mask, multiplied by 4. The

following pre-defined constants may be used:

X1 = 0 PPIXC0 = 0

X2 = 4 PPIXC3 = 4

Y1 = 8 PPIYC0 = 8

Y2 = 12 PPIYC3 = 12

Z1 = 16 PPIZC0 = 16

Z2 = 20 PPIZC3 = 20

PPIX = 0 PPIYC7 = 8

PPIY = 8 EXT0 = 0

PPIZ = 16 ADC0 = 0

ADC2 = 8

DAC2 = 8

DAC4 = 16

SATRIG = 12

Returns short: OK
