Notes: 1. When BCR1.A5PCM = 0, high-Z.
2. When BCR1.A6PCM = 0, high-Z.
3. When BCR1.DRAMTP (2–0) ≠ 101, high-Z.
4. When WCR2 register wait setting is 0, disabled.
5. When BCR2.PORTEN = 0, high-Z. When BCR2.PORTEN = 1, dependent on PCTR
register.
6. When BCR2.PORTEN = 0, high-Z. When BCR2.PORTEN = 1, D31 and D30 only data
output.
