will be I/OD pin, if set to 1 the pin GPIO17 is I/O pin.
Enable GPIO26 drive high buffer. If this bit is set to 0, the pin GPIO26
will be I/OD pin, if set to 1 the pin GPIO26 is I/O pin.
Enable GPIO25 drive high buffer. If this bit is set to 0, the pin GPIO25
will be I/OD pin, if set to 1 the pin GPIO25 is I/O pin.
Enable GPIO24 drive high buffer. If this bit is set to 0, the pin GPIO24
will be I/OD pin, if set to 1 the pin GPIO24 is I/O pin.
Enable GPIO23 drive high buffer. If this bit is set to 0, the pin GPIO23
will be I/OD pin, if set to 1 the pin GPIO23 is I/O pin.
Enable GPIO22 drive high buffer. If this bit is set to 0, the pin GPIO22
will be I/OD pin, if set to 1 the pin GPIO22 is I/O pin.
Enable GPIO21 drive high buffer. If this bit is set to 0, the pin GPIO21
will be I/OD pin, if set to 1 the pin GPIO21 is I/O pin.
