NOTES:
1. Make sure registers PD7 and PD9 are written to by the next instruction after setting the PRC2 bit in the PRCR
register to 1 (write enabled).
2. During memory expansion and microprocessor modes, the PDi register for the pins functioning as bus control
pins (A0 to A19, D0 to D15, CS0 to CS3, RD, WRL/WR, WRH/BHE, ALE, RDY, HOLD, HLDA, and BCLK)
cannot be modified.
* Not available memory expansion and microprocessor modes in T/V-ver..
3. When using the ports P11 to P13, set the PU37 bit in the PUR3 register to 1 (usable).
4. Registers PD11 to PD13 are only in the 128-pin version.
