(Cont.)
The output of the PSD5XX interrupt controller is connected to one ot the interrupt inputs
on the 80C186 microprocessor. The PSD5XX interrupt controller interrupts the
microprocessor in response to the timer underflow. In response to this interrupt, the
microprocessor reads the INTERRUPT PRIORTY STATUS REGISTER and updates the
respective timer image register. The output of a timer makes a high to low transition when a
timer count expires.The high to low transition of the timer is inverted and is used to preload
the respective timer from the last image register. In the slewing mode the IMAGE
REGISTER for a timer does not need to be preloaded on each step interrupt. As the timer
count expires the old count will be pre-loaded automatically. Figure 9 shows the logic
configuration for a given axis and Figure 10 shows the *.abl file listing for the preloading
capability of the timers.
