<OE2SEL = 0> OE2 = low-level, gate output ON
Remark When IFSEL = H (when using the control pins), the GCS, GCL, and GDA pins are pulled down to low level, so
be sure to leave these pins open.
When IFSEL = L (when using the serial interface), DCON, RGONR, VCD2, VMS, FS0, FS2, CLS0, RGON,
VSEL, EXRV, ACS0, SCN0, SCN1, SCN2, PUPT0, DUPF0 pins should be left open.
