Clock and Timer Functions
Figure 2-12 shows a block diagram of the ispPAC-POWR1014/A’s internal clock and timer systems. The master
clock operates at a fixed frequency of 8MHz, from which a fixed 250kHz PLD clock is derived.
Figure 2-12. Clock and Timer System
The internal oscillator runs at a fixed frequency of 8 MHz. This signal is used as a source for the PLD and timer
clocks. It is also used for clocking the comparator outputs and clocking the digital filters in the voltage monitor cir-
