Each CLB output signal passes through an external multiplexer that intersects a specific peripheral signal, see Figure 32-9. The output of the multiplexer is connected to the destination of the original peripheral signal and the default multiplexer setting is that the peripheral signal is passed through. The multiplexer is controlled by bit[n] in the CLB output enable register CLB_OUT_EN.
For example, if the CLB1 OUT0 must override the EPWM1A signal, the OUPTUT ENABLE bit for OUT0 must be set to 1.
Table 32-4 shows the allocation of peripheral signals and the CLB outputs.
