[Note 1]
: When reset (in address/data separate mode)
"General-purpose input port" is selected in address/data multiplex mode.
*1 : In the event of a reset in address/data separate mode, the P2PU bit in the P2MD register is set
to "1" and the data pins (the 8 bits D[15:8]) are pulled up.
[Note 2]
Setting P2M to "0" in address/data multiplex mode, is prohibited.
[Note 3]
When the bus authority is granted, D15 to D8 go to high impedance.
