What is the frequency of Smclk in MSP430?
After a device reset, the MSP430 MCU sources the subsystem master clock (SMCLK) from the DCO configured to run at 16 MHz. The device then executes a frequency command stored in FRAM that divides SMCLK to the last known frequency before device reset.
What is the frequency of AC LK?
The frequency of ACLK is 2500 Hz. The frequency of BCLK is 32768 Hz.
What is the difference between smclk and aclk?
The master clock (MCLK) is derived from any of the four oscillators, and it drives the cpu. The sub-main clock (SMCLK) is derived from any of the four oscillators, and it drives peripherals. The auxiliary clock (ACLK) is derived from either VLOCLK or LFXT1CLK, and it drives peripherals.
What is the frequency of the DCO in MSP430?
The DCO is digitally controlled because its frequency be changed from several hundred kHz up to 25MHz. The MSP430 can also use external crystals with internal oscillator circuitry to generate both low frequency (32kHz) and high frequency (Up to 25MHz) clocks that are as accurate as the crystal used.
