0, 1 Port P7 data input bits

(P7D0, P7D1)

When only OP1 = “0” and

OP0 = ”1,” input data is

valid.

(See note)

Indeterminate

D-A/AD3 function selection

bit (P7D2)

Nothing is assigned. These bits are write disable bits.

When these bits are read out, the values are indeterminate.

Notes 1: When inputting data from the S out pin, set “FF16” to the serial

I/O register.

2: When using ports P4 4–P47 as serial I/O pins, set bit 1 of the

serial I/O control register to “0.”
