Detailed Description

Polls the High-Speed Analog Comparator on channel 0 and routes the decision to the board LEDs: LED1 toggles while the output reads high, LED2 while it reads low, LED3 on an init failure. No UART output.

On a bare EVM the IVCMP input floats, so the comparator's decision is not ground truth – nothing on the board holds that pin at a known voltage, and LED1 versus LED2 only proves the chip is alive. The unattended gate therefore probes g_acmphs_compare_tick over SWD, which shows the poll loop running and the driver not faulting. Asserting the analog decision itself means wiring a known reference onto IVCMP / IVREF.
