IP-Quadrature GE quadrature counting pulse input in quadrature mode
Each channel can be programmed to count in orthogonal mode using X and Y inputs. Alternatively, each channel can be operated as a universal counter, where the X and Y inputs are input as count up and count down pulses, or as count input and direction input, respectively, for interrupts, with backward counting often preferred because underflows (” borrows “) may be programmed to cause interrupts. Interrupts may also occur on Match. This default/comparison register can be programmed to any value, including $FFFFFF or $000000 (to simulate an “overflow” interrupt). Both underflows and overflows have dedicated triggers that can be read by reading the counter’s control register. The counter registers and triggers are accessed as registers in the LS7166 counter IC. The LS7166 IC has two count inputs, called A and B on the chip, and two control inputs that can each be programmed for one of the two functions. The A and B count inputs and the two control inputs on the LS7166 are driven by the Xilinx LCA, which provides routing and polarity capabilities. Ip-quadrature’s X input is usually routed to the A input, and IP’s Y input is routed to the chip’s B input. The Z input of the IP is routed to either of the two control inputs on the chip. The polarity of all three input signals is individually programmable. There is a software-controlled gating of the bits implemented in the Xilinx LCA for Z input. Software-controlled gating is used for the X and Y inputs implemented in LS7166.
Generally, count mode and control functions are available independently. Figure 9 lists the basic count mode and Figure 10 lists the basic control functions. If the control function is not required, the Z control input may not be connected. The 24-bit default/compare register has two functions. A specific value is loaded into the counter when the host software wants it, which is typical for counting down. This register can also be used if the appropriate control function has been programmed. The 24-bit default/compare register is also used to generate an interrupt for a specific value when the counter is reached. Note that this register can be used to first load the counter and then change to support the match interrupt feature. When the counter is in operation. Multiple Match interrupts can be programmed by reloading this register after each interrupt (make sure that the counter has not passed the required breakpoint after this is done).
