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

6. When BCR2.PORTEN = 0, high-Z. When BCR2.PORTEN = 1, D31 and D30 only data

output.
