Port C Signals (Continued)
Baud-Rate Generator 4 Output
The CPM supports up to 8 BRGs used internally by the bank-of-clocks
selection logic and/or to provide an output to one of the 8 BRG pins.
Clock 4
The CPM supports up to 10 clock input pins 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 MSC8101 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.
Baud-Rate Generator 5 Output
The CPM supports up to 8 BRGs used internally by the bank-of-clocks
selection logic and/or to 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 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.
