Task 11: Reset Functions
Performs various reset function on the point list and function/curve assignment tables. Also pro-
vides a subtask to set the sample and hold settle time.
Notes:
1. SUBTASK 5 is provided to set the sample and hold settle time. High speed 80286, 80386, and
80486 computers often will start a conversion before the sample and hold has had time to settle
after changing a channel on the AT16-P. A value of 25-50 is usually sufficient for an 80386
machine.
Input:
params[0]:
Subtask to perform, 1, 2, 3, 4 or 5.
1: Reset the point list index to first point address in the point list.
2: Clears all point addresses from the point list.
3: Resets the point list to the default conditions, as described in TASK 0.
4: Clears all curve and scaling assignments.
5: Set the sample and hold settle time.
params[1]:
settle time count
Output:
Data:
None.
Error Codes:
status = 0: No error.
status = 1: Invalid task number, task > 17, or driver not initialized.
status = 15: Invalid reset sub task, not between 0 and 5.
