Modulation Control

The modulation control part combines the different modulation sources (CC6x_T12_o
and COUT6x_T12_o are the output signals that are configured with
CC6xPS/COUT6xPS; MOD_T13_o is the output signal after T13 Inverted Modulation
(T13IM)). Each modulation source can be individually enabled per output line.
Furthermore, the trap functionality is taken into account to disable the modulation of the
corresponding output line during the trap state (if enabled).

Figure 14-11 Modulation Control of T12-related Outputs

For each of the six T12-related output lines (represented by “x”) in the

Figure 14-11

:

•

T12MODENx enables the modulation by a PWM pattern generated by timer T12

•

T13MODENx enables the modulation by a PWM pattern generated by timer T13

•

MCMPx chooses the multi-channel patterns

•

TRPENx enables the trap functionality

•

PSLx defines the output level that is driven while the output is in the passive state
