MSC8101 Technical Data
Baud-Rate Generator 5 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 5
When selected, CLK5 is a source for the SIU timers via BRG1O.
See the System Interface Unit (SIU) chapter in the MSC8101
Technical Reference manual for additional information. If CLK5 is
not enabled, BRG1O uses an internal input. If TMCLK is enabled
(see PC26 below), the BRG1O input to the SIU timers is disabled.
Timer 3/4: Timer Gate 2
The timers can be gated/restarted by an external gate signal. There
are two gate signals: TGATE1 controls timer 1 and/or 2 and
TGATE2 controls timer 3 and/or 4.
Baud-Rate Generator 6 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 6
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 3: Timer Out 3
The timers (Timer[1–4]) 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 connect internally to the input of another timer, resulting in
a 32-bit timer.
Timer Clock
When selected, TMCLK is the designated input to the SIU timers.
When TMCLK is configured as the input to the SIU timers, the
BRG1O input is disabled. See the System Interface Unit (SIU)
chapter in the MSC8101 Technical Reference manual for additional
information.
