Baud-Rate Generator 3 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 3
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 2
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.
SCC1: Clear to Send, Collision
Typically used in conjunction with RTS. The MSC8103 SCC1
transmitter sends out a request to send data signal (RTS).
The request is accepted when CTS is returned low. CLSN is
the signal used in Ethernet mode. See also PC15.
Baud-Rate Generator 4 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 4
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 1
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.
Timer 2: Timer Output 2
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 be connected internally to the input of
another timer, resulting in a 32-bit timer.
SCC2: Clear to Send, Collision
Typically used in conjunction with RTS. The MSC8103 SCC2
transmitter sends out a request to send data signal (RTS).
The request is accepted when CTS is returned low. CLSN is
the signal used in Ethernet mode. See also PC13.
