R/W
Programs the direction of pins DIO7 through DIO1. Writing a 1 indicates an output. A bit
is ignored if the corresponding pin is not configured as DIO. See DIO_PV and DIO_PW
for special options for DIO6 and DIO7. See DIO_EEX[1:0] for special options for DIO4
and DIO5.
DIO_DIR1[7:5,

R/W
Programs the direction of pins DIO15 through DIO8. Writing a 1 indicates an output.
A bit is ignored if the corresponding pin is not configured as DIO. See DIO_PX and
DIO_PY for special options for the DIO8 and DIO9 outputs.
DIO_DIR1[4] controlling DIO12 is only applicable to the 71M6534.
