NOTE:
1. Ports must be enabled using the PACR register.
In 48-pin package, set PACR2, PACR1, PACR0 to "100
2 "
In 42-pin package, set PACR2, PACR1, PACR0 to "001
2 "
NOTE:

NOTE:
1. Make sure the PD9 register is written to by the next instruction after setting the PRC2 bit in the PRCR
register to "1" (write enabled).
