Tool/software:
Hello,
I'm working on an application with version 5.10.00.48 of the simplelink SDK, running on a custom board that requires power consumption to be as low as possible. The application is based on the simple_peripheral example project, hence it uses pretty much the same power management configuration, including allowing transitions into Standby power mode. As part of this task, I'm trying to disable any peripherals while not in use through the TI RTOS drivers functions e.g. SPI_close. When doing so, I notice that the clock gate registers related to the peripheral being closed (e.g. SSICLKGR, SSICLKGS, SSICLKGDS) are updated to disable the peripheral's clock in the different power modes. However, I don't notice any change in power consumption. If I'm interpreting the microcontroller data sheet correctly, the current consumption of e.g. SSI module with clock enabled in idle mode should be 61uA. When disabling this and other module's clocks, should I expect a reduction in current consumption around the values specified in the data sheet? Is there any other indicator of a peripheral's state besides the clock gate registers?
Thanks,
Julian
