4 IO Voltage Domains and Signal Levels

Migrating to AM62Lx requires a review of IO bank voltage configurations. AM62x offers broad flexibility with dual-voltage (1.8V/3.3V) IO banks, whereas AM62Lx has designated some banks for dual-voltage and made the rest 1.8V only. Moreover, AM62Lx introduces new buffer types (1.8V-specific) and there are changes in which signals are fail-safe. This section discusses a high-level overview of those differences.
