Figure 8-4. Clock Gating Power Savings

The power disable control register provides control bits that can enable or disable the clock to several

peripherals such as, PCM, CPCC, digital filters, front ends, DPWMs, UARTs, ADC-12 and more.

By default, all these controls are enabled. If a specific peripheral is not used the clock gate can be disabled

in order to block the propagation of the clock signal to that peripheral and therefore reduce the overall current

consumption of the device. The power savings chart displays the power savings per module. For example there

are 4 DPWM modules, therefore, if all 4 are disabled a total of ~20 mA can be saved.
