The internal oscillator drives the 25MHz core clock without an external crystal, so the supply rail sees burst current during sigma-delta sampling bursts. TI's standard MSP430 decoupling guideline is a 0.1µF ceramic per VCC pin under the package plus a bulk 4.7µF cap — the brown-out reset threshold is below 1.8V, so keep supply droop above that level under peak peripheral loading."},{"question":"How many analog input pins does the 8x10b ADC use versus the 7×24b sigma-delta channels?","answer":"The 8×10-bit SAR ADC and the 7×24-bit sigma-delta converter are separate on-chip peripherals. The 128-LQFP package routes 90 I/O pins total; the sigma-delta inputs consume six pins for the three voltage and three current channels per phase, and the SAR ADC uses a subset of the remaining analog-capable pins for housekeeping measurements. Pin-sharing between the two converters is die-level fixed and the specific routing within the 128-LQFP pinout requires the TI datasheet pinout diagram to confirm which physical pins map to each function.
