Baud-Rate Generator 7 Output
The CPM supports up to 8 BRGs. The BRGs can be used internally
by the bank-of-clocks selection logic and/or provide an output to one
of the 8 BRG pins.
Clock 7
The CPM supports up to 10 clock input pins. The clocks are sent to
the bank-of-clocks selection logic, where they can be routed to the
controllers.
Timer Input 4
A timer can have one of the following sources: another timer,
system clock, system clock divided by 16 or a timer input. The CPM
supports up to 4 timer inputs. The timer inputs can be captured on
the rising, falling or both edges.
DMA: Data Acknowledge 2
DACK2, DREQ2, DRACK2 and DONE2 belong to the SIU DMA.
DONE2 and DRACK2 are signals on the same pin and therefore
cannot be used simultaneously. There are two sets of DMA pins
associated with the PIO ports.
Baud-Rate Generator 8 Output
The CPM supports up to 8 BRGs. The BRGs can be used internally
by the bank-of-clocks selection logic and/or provide an output to one
of the 8 BRG pins.
Clock 8
The CPM supports up to 10 clock input pins. The clocks are sent to
the bank-of-clocks selection logic, where they can be routed to the
controllers.
Timer Input 3
A timer can have one of the following sources: another timer,
system clock, system clock divided by 16, or a timer input. The CPM
supports up to four timer inputs. The timer inputs can be captured
on the rising, falling, or both edges.
Timer 4: Timer Out 4
The timers (Timer1–4]) can output a signal on a timer output
(TOUT[1–4]) when the reference value is reached. This signal can
be an active-low pulse or a toggle of the current output. The output
can also be connected internally to the input of another timer,
resulting in a 32-bit timer.
DMA: Data Request 2
DACK2, DREQ2, DRACK2, and DONE2 belong to the SIU DMA.
DONE2 and DRACK2 are signals on the same pin and therefore
cannot be used simultaneously. There are two sets of DMA pins
associated with the PIO ports.
