/* GPIOs to use for tracing of esp_pm events.

|
* Array structure: s_trace_io[core_id][event_type]
|
|
* - First dimension: core_id, indexed from 0 to (portNUM_PROCESSORS - 1)
|
|
* - Second dimension: event_type, indexed by esp_pm_trace_event_t enum values
|
|
*
|
|
* Event type mapping (second dimension index):
|
|
* 0: ESP_PM_TRACE_IDLE
|
|
* 1: ESP_PM_TRACE_TICK
|
|
* 2: ESP_PM_TRACE_FREQ_SWITCH
|

* 4: ESP_PM_TRACE_ISR_HOOK
|
|
* 5: ESP_PM_TRACE_SLEEP
|

|
|
* NOTE: These GPIOs can be modified for debugging purposes.
|
|
* WARNING: Do not use GPIOs that are utilized as MSPI IOs, otherwise the chip may crash.
