ispPAC-POWR604 Data Sheet
The timers can cover a range from 32us to 524ms for the internal oscillator. Longer delays can be achieved by
using the external clock as an input.

1. Timer values based on 250kHz clock.
For design entry, the user can select the source for the clock and the PAC-Designer software will calculate the
appropriate delays in an easy-to-select menu format.
The control inputs for Timer1 and Timer2 can be driven by any of the eight PLD macrocell outputs. The reset for the
timers is a function of the Global Reset pin (RESET), a power-on reset or when the timer input goes low. The wave-
forms in Figure 2-6 show the basic timer start and reset functions. Timer and clock divider values are speci?ed in
during the design phase using the PAC-Designer software, while simple pull-down menus allow the user to select
the clocking mode and the values for the timers and the PLD clock.

Note that if the clock module is con?gured as “slave” (i.e. the CLK is an input), the actual time-out of the two timers
is determined by the external clock frequency.
