* @brief Checks if the EEPROM is currently writing.

* This function reads the MCP4461 status register to determine if an EEPROM write operation is in progress.
* If the EEPROM is no longer writing, the timeout flag (`last_eeprom_write_timed_out_`)
* is reset to allow normal operation in future calls of `is_eeprom_ready_for_writing_()`.

* Behavior:
* - If the EEPROM is **writing**, the function returns `true`.
* - If the EEPROM is **not writing**, the function returns `false` and resets `last_eeprom_write_timed_out_`.
*
* @return `true` if the EEPROM is currently writing.
* @return `false` if the EEPROM is not writing (also resets the timeout flag).

/**
* @brief Checks if the EEPROM is ready for a new write operation.
*
* This function ensures that the EEPROM is not actively writing.
* It can either return the current status immediately or wait until the EEPROM becomes ready.
*
* Behavior:
* - If `wait_if_not_ready` is `false`, the function returns the current readiness status immediately.
* - If `wait_if_not_ready` is `true`:
* - The function waits up to `EEPROM_WRITE_TIMEOUT_MS` for the EEPROM to become ready.
* - If the EEPROM remains busy after the timeout, the `last_eeprom_write_timed_out_` flag is set to `true`,
* preventing unnecessary waits in future calls.
* - If the EEPROM becomes ready within the timeout, the function returns `true`.
*
* @param[in] wait_if_not_ready Specifies whether to wait for EEPROM readiness if it is currently busy.
* - `true` → Waits for completion (up to `EEPROM_WRITE_TIMEOUT_MS`).
* - `false` → Returns the current readiness status without waiting.
*
* @return `true` if the EEPROM is ready for a new write.
* @return `false` if:
* - The last write attempt **timed out** (`wait_if_not_ready = true`).
* - The EEPROM is still busy (`wait_if_not_ready = false`).
