The following parameters are defined for the 8 bit timer module.
It is possible to simulate changes in the supply level from 0V to 5V with the use of
the scroll bar. The minimum precision is 0.01V, although steps of 0.1V can be
obtained using the page-up and page down function keys. It should be noted that
reducing the supply voltage to 0V will not stop the software simulation of the
microcontroller.
