8.2 Internal registers
8.2.74 Input_Filter_Mask
Description: This register controls filtering of each of the eight IO pins that are used as digital
inputs. If the bit corresponding to the input number is set in this register, the input value
will be filtered to a new logical level is only accepted after that level has been measured
on the hardware pin for the number of milliseconds specified in register 136. If the bit is
not set, the input will be updated directly from the hardware value every 100
microseconds. Please read the section on Digital Input filters in this manual.
8.2.75 Input_Filter_Cnt
Description: The filtering of all of the eight digital inputs is controlled by the value in this register
together with register 135. The input must be sampled at the same value for the specified
number of milliseconds in this register to be accepted as the new filtered value. See also
the section on Digital Input Filters in this manual.
8.2.76 Inpos_Mask
Description: Selects which one of the eight IO pins to use for the dedicated function of In Position
Output.
Exactly one bit must be set, and the IO pin must be configured in register 125 as an
output.
The In Position output will then be set after a movement has completed.
Example: If output “n” is to be used for the In Position Output, write 2^ (n-1) to this register.
8.2.77 Error_Mask
Description: Selects which one of the eight IO pins to use for the dedicated function of Error Output.
Exactly one bit must be set, and the IO pin must be configured in register 125 as an
output.
The Error Output will set be set when any error is set.
See register 35 ( Err_Bits , page 201) for more information on errors.
Example: If output “n” is to be used for the Error Output, write 2^ (n-1) to this register.
