Counter/Timer Clock Input
Table 22. DLCY, Scale Bit and DIV to Generate Different Clock Divisions
Sample Calculation of Timer Input Clock
External input clock to the PSD5XX is 8 MHz.
If required Counter/Timers 0 – 3 count frequency is 1 MHz then
The Counter/Timer CLOCK Input
=
1 MHz =
Therefore from Table 22 when (DIV) = 8, the Scale-Bit in the “Global Command Register” is
set to a 0 and the DLCY register to a value of 4.
