0 W2048 = SV0 W2304 = PV0
1 W2049 = SV1 W2305 = PV1
: : :
255 W2303 = SV255 W2559 = PV255
Where SV is Set Value and PV is Present Value.

Be sure you understand the programming of the timer/counter thoroughly. If you
change the above registers while the program is running or program them
incorrectly, errors or damage may occur.
