Configuring the UDC Module’s Registers 3-63
Scans Per Interrupt Register 2001
The Scans Per Interrupt register contains the number of times a UDC
task is to be scanned between updates of the Nth scan application
registers. Sug. Var. Name: SPI%
Units: N/A
Range: See below.
Access: Read/Write
Note that you must write the desired value to this register before you turn on CCLK. The default value is zero
(i.e., not applicable because an interrupt is not being used but is updated each scan). One is a permissible
value. If a hardware EVENT is defined in an AutoMax application task, this register will also specify when the
interrupt occurs, i.e., every Nth scan. See chapter 4 for more information on interrupts.
