NOTES:
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).
2. Set the PACR register.
In 80-pin package, set bits PACR2, PACR1, PACR0 to 011
2.
In 64-pin package, set bits PACR2, PACR1, PACR0 to 010
2.
NOTE:
1. Set the PACR register.
In 80-pin package, set bits PACR2, PACR1, PACR0 to 011
2.
In 64-pin package, set bits PACR2, PACR1, PACR0 to 010
