(7) Port mode register 6 (PM6)
This register sets the input/output of port 6 in 1-bit units.
When using the P60/SCL0 pin as clock I/O and the P61/SDA0 pin as serial data I/O, clear PM60 and PM61,
and the output latches of P60 and P61 to 0.
Set IICE0 (bit 7 of IIC control register 0 (IICC0)) to 1 before setting the output mode because the P60/SCL0
and P61/SDA0 pins output a low level (fixed) when IICE0 is 0.
PM6 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
