PCLK—Prescaler Clock Select
CPE—Counter Prescaler Enable
CLK—Clock
MOTOROLA
These bits determine which sources of interrupts, TO, TG, and TC, are enabled to
generate an interrupt request to the CPU32. Table 8-3 lists which interrupts are enabled
for all bit combinations.
This bit selects which clock is used for the counter clock.
The prescaler continues to decrement regardless of how PCLK is set.
The TOUTx of one timer can be fed externally into the TINx input of the other timer,
resulting in a 32-bit counter if the prescalers are not used and a 48-bit counter if they
are used.
1 = The TGATE signal is enabled to control the enabling and disabling of the
0 = The TGATE signal has no effect on the timer operation.
1 = The counter is decremented by the prescaler output tap as selected by the POT
0 = The counter is decremented by the selected clock.
1 = The selected clock is enabled. If the TGE bit is set, then TGATE must also be
0 = The selected clock is held high, halting the prescaler and counter.
1 = The selected clock is taken from the TINx input.
0 = The selected clock is one-half the system clock's frequency.
