What is the ACLK in MSP430?
TACLK, TA0, and TA1 are associated with Timer_A; TACLK can be used as the clock input to the timer, while TA0 and TA1 can be either inputs or outputs. These can be used on several pins because of the importance of the timer. A0−, A0+, and so on, up to A4±, are inputs to the analog-to-digital converter.
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 ACLK in MSP430?
Clocks on the MSP430 Launchpad
After power-up, MCLK and SMCLK are sourced from DCOCLK at about 1.1MHz. ACLK is sourced from LFXT1CLK in LF mode. The Launchpad comes with an option 32kHz crystal in the box that needs to be installed by the user.
