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 significance of a 32.768 kHz watch crystal for ACLK?
Understanding 32.768 kHz Crystals
Their specific frequency allows them to divide down to 1 Hz, equivalent to one second in frequency, making them the basis for all day, date, and timekeeping functions for any electronic design.
