Note 1: * shows that there is no relationship to the configuration of the corresponding function.

Note 2: One of ECC, PIO[15:8] and ETHERC0 can be selected (can't use simultaneously).

One of ACLC and ETHERC0 can be selected (can't use simultaneously).

One of ATA and NDFMC can be selected (can't use simultaneously).

One of ISA and NDFMC can be selected (can't use simultaneously).

(Operation is not guaranteed when these functions that cannot be used simultaneously are set up)

Note 3: It shows that these terminals are multiplexed under each function.

Note 4: Blank shows that the terminal isn't multiplexed with the function.

For example, when only two pieces, ATA and SPI are selected, functions other than DMAREQ[3],

DMAREQ[1], DMAACK[3], DMAACK[1], PIO[0] can be used.
