I would like to operate the SPESENSE register directly in the Arduino IDE 1.8.13 environment.
I read the official development guide Fast digital I/O below.
https://developer.sony.com/develop/spresense/docs/arduino_developer_guide_ja.html#_fast_digital_io
In Arduino, byte input=PINB|~0b00000011; is used to manipulate registers and
I was reading D8 and D9 pin inputs at the same time, but how should I program them in SPESENSE?
If I know how to set the register, I can program it myself...
Thank you for your cooperation.
I think the register specification is listed in LSI's User Manual.

If you look at this document and the source code for the Spresense SDK, see
GPIO is divided into one register for each pin, so I don't think I can read it at the same time.
Since it is multi-core, each core may have a separate register so that the pins can be operated independently.
