Note:
  1. A0/NBS0, A1, A12, A19 and A20, NCS0, NCS2/NANDCS, NRD, NWR0/NWE, NWR1/NBS1 are multiplexed on PD[13:4].
  2. NWR1 enables upper byte writes. NWR0 enables lower byte writes.

Note:
  1. The NFD0_ON_D16 switch is used to select NAND Flash path on D[7:0] or NANDDAT[7:0] depending on memory power supplies. This switch is located in the SFR_CCFG_EBICSA register in the Special Function Register.
