Timers

There are 10 virtual timers. Each timer has an input flag, an output flag,

and a reload value.

T1IN, T2IN ... T10IN // input flags

T1O, T2O ... T10O // output flags

T1RLD, T2RLD ... T10RLD // reload values

When a timer input (for example, T1IN) goes from 0 to 1, the counter

starts counting from the reload value (for example, T1RLD) down, one

count every virtual driver tick (25 milliseconds). The output flag (T1O) is

set to 1 when the count reaches zero. The output is forced to zero when-

ever the input is set to zero.
