Sample program
(H0803)
In this example, 2051 (H0803) is set in SW16. As a result, the quadrature bi-pulse
counter is selected.
When R010 comes ON, the data 150000 is set into the comparison value 1 register
(SW19SW18), and 200000 is set into the co mpariso n value 2 register (SW21SW20).
While R010 is ON, the soft-gate (S240), the interrupt enable flag 1 (S241) and the
interrupt enable flag 2 (S249) are set to ON to enable the counter operation.
The count value is stored in SW23SW22.
When R010 is OFF and R011 comes ON, the count value is preset to the data of
D0101D0100.
