I cannot use PSRAM on the ESP32-S3-WROOM-N8R8.

I configured PlatformIO as follows to use the ESP32-S3-WROOM-N8R8:

[env:esp32-s3-devkitc-1]
platform = espressif32
; board = esp32-s3-devkitc-1
board = esp32-s3-devkitc1-n8r8
framework = arduino
monitor_speed = 115200

board_build.arduino.memory_type ...

I am developing esp32 in Arduino environment.
But is there no way to implement rx interrupt in Arduino environment?
It seems possible in esp-idf, but how can I implement rx interrupt in Arduino environment?
Thank you.
