## Capping
To protect the battery from excessive strain, clocks requested from config may be capped before applying, depending on your current profile:

### Real Volts
voltage readings from devices: CPU/GPU/MEM/SOC
### Real Temps
temperature readings from thermal sensors: CPU/GPU/MEM/PLL/AO
### Cpu volt bug fix
fixes bug present in official driver
### Reversenx sync
automatically changes profile when reversenx state is changed

### Advanced
The `[values]` section allows you to alter timings in sys-clk, you should not need to edit any of these unless you know what you are doing. Possible values are:
| Key | Desc | Default |
|:-----------------------:|-------------------------------------------------------------------------------|:-------:|
|**temp_log_interval_ms** | Defines how often sys-clk logs temperatures, in milliseconds (`0` to disable) | 0 ms |
|**freq_log_interval_ms** | Defines how often sys-clk logs real freqs, in milliseconds (`0` to disable) | 0 ms |
|**power_log_interval_ms**| Defines how often sys-clk logs power usage, in milliseconds (`0` to disable) | 0 ms |
|**csv_write_interval_ms**| Defines how often sys-clk writes to the CSV, in milliseconds (`0` to disable) | 0 ms |
|**poll_interval_ms** | Defines how fast sys-clk checks and applies profiles, in milliseconds | 300 ms |
|**uncapped_clocks** | Removes clock cappings | OFF |
|**override_boost_mode** | Overrides official boost mode with user set profile clocks | OFF |
|**auto_cpu_boost** | Sets cpu clock to boost clock when core#3 load ≥ 90% | OFF |
|**sync_reversenx** | Overrides profile to match reversenx state | ON |
