User manual
5.6.1.4.1 Invalid frequency (device maximum clock rate exceeded)
5.6.1.4.2 An applicable power setup
5.6.1.4 Code examples
The following examples illustrate some of the set_power features discussed above.
command[0] = 60;
command[1] = PWR_CPU_PERFORMANCE;
command[2] = 60;
(*rom)->pWRD->set_power(command, result);
The above setup would be used in a system running at the main and system clock of
60 MHz, with a need for maximum CPU processing power. Since the specified 60 MHz
clock is above the 50 MHz maximum, set_power returns PWR_INVALID_FREQ in
result[0] without changing anything in the existing power setup.
command[0] = 24;
command[1] = PWR_CPU_EFFICIENCY;
command[2] = 24;
(*rom)->pWRD->set_power(command, result);
The above code specifies that an application is running at the main and system clock of
24 MHz with emphasis on efficiency. set_power returns PWR_CMD_SUCCESS in
result[0] after configuring the microcontroller’s internal power control features.
