Types and enums

All public device types are C-compatible and declared in drv8316/drv8316_types.h. Enum families represent register lock, SDO output, slew rate, PWM mode, thermal warning, overvoltage protection and level, 100% PWM frequency, OCP mode/level/retry/deglitch/CBC, driver state, current-sense gain, ASR, AAR, current-limit recirculation, buck state/voltage/current limit/ sequencing, and delay target/compensation.

DRV8316_Diagnostics_t stores the raw ic_status, status_1, and status_2 bytes. Decode them with masks from drv8316_registers.h. The snapshot changes only after refreshDiagnostics().
