Summary

Corrects the K3 dual-voltage GPIO (VCC1833) absolute maximum supply voltage from 1.98V/3.63V to 1.98V/3.465V in §5.2.1 per hardware team review.

Scope — absolute maximum only

Recommended operating conditions (§5.1 / §4.1) are intentionally left unchanged at 1.98V/3.63V. Only the absolute maximum rating is corrected.

Affected rails: VCC1833_GPIO1/2/4/5, VCC1833_QSPI, VCC1833_MMC1.

AVDD33_* USB 3.3V rails also show 3.63V and are not affected — they are single-voltage 3.3V rails.
