CLKCONCMD is a command used in the context of microcontrollers and refers to the clock control command. It is used to control the operation and frequency of the clock signal of the microcontroller. The CLKCONCMD is responsible for configuring the system clock source, setting the clock frequency and dividing the clock signal. This command is specific to each microcontroller and its implementation may vary depending on the manufacturer and model.

CLKCONCMD (Clock Control Command) is a register in the CC2530 and CC2531 System-on-Chip (SoC) devices from Texas Instruments. It is used to control the clock settings of the device, including the system clock frequency and the division ratio of the auxiliary clock.
CLKCONCMD has several different fields that can be set to control the clock settings. These fields include:
- SCLK_HF_SRC: Selects the source of the high-frequency system clock (SCLK_HF). It can be set to either the crystal oscillator or the internal RC oscillator.
- SCLK_HF_BIT: Enables or disables the high-frequency system clock output.
- SCLK_MF_SRC: Selects the source of the medium-frequency system clock (SCLK_MF). It can be set to either SCLK_HF or the low-frequency system clock (SCLK_LF).
- SCLK_DIV: Sets the division ratio for the auxiliary clock (SCLK_AUX).
- SCLK_LF_SRC: Selects the source of the low-frequency system clock (SCLK_LF). It can be set to either the external crystal oscillator or the internal RC oscillator.
By configuring these fields, the device's clock settings can be optimized for the specific application requirements, balancing power consumption and performance.

CLKCONCMD (Clock Control Command) is a command used in the IEEE 802.15.4 standard for wireless personal area networks (WPANs). It is used to control the clock source and frequency of the WPAN device. The CLKCONCMD is a register that can be accessed by the WPAN device's microcontroller. The register contains various bits that can be set or cleared to control the clock source and frequency. For example, the CLKCONCMD can be used to switch between the internal oscillator and an external crystal oscillator, or to adjust the frequency of the oscillator. The CLKCONCMD is an important command for ensuring that the WPAN device operates at the correct frequency and with the correct timing.
