[Note 1]
: When reset (in address/data separate mode)
"General-purpose input port" is selected in address/data multiplex mode . pin No. 95 and 96,
however, are set as RWSEL and AS, respectively.
*1 : In the event of a reset in address/data separate mode , the P1PU bit in the P1MD register is set
to "1" and the data pins (the 8 bits D[7:0]) are pulled up.
<<>> : These pins are set in address/data multiplex mode .
Setting invalid: In address/data multiplex mode , pin No. 95 is used only for RWSEL, and pin No. 96 is used
only for AS; the P1MD and P1DIR settings are invalid.
[Note 2]
Setting P1M to "0" in address/data multiplex mode is prohibited.
[Note 3]
When the bus authority is granted, D7 to D0, AS, and RWSEL go to high impedance.
