NOTES:
1. For P5_3, use the PM07 bit in the PM0 register, bits PM15 and PM14 in the PM1 register, and bits
CM01 and CM00 in the CM0 register to select CLKOUT or ALE output.
2. For P5_4 and P5_6, use bits PM15 and PM14 to select ALE output.
3. P7_0 and P7_1 are N-channel open drain output ports.
4. These ports are provided in the 144-pin package only.
