6.13.1 Clock Specifications

The CC350xE device uses two clocks for operation:
  • A fast clock running at 52 MHz for active MCU functions and peripherals, as well as WLAN/Bluetooth LE.
  • A slow clock running at 32.768 kHz for low power modes. The slow clock can be generated internally or externally.
