I/O port P10
In single-chip mode, these pins have the same functions as port P0. In memory
expansion mode or microprocessor mode, these pins become data I/O pins and
operate as follows:
(1) When using 16-bit width as external data bus width:
Accessing external memory
<When reading>
Pins’ value is input into low-order internal data bus (DB
0
to DB
7
).
<When writing>
Value of low-order internal data bus (DB
0
to DB
7
) is output to these pins.
Accessing internal memory
<When reading>
These pins become high impedance.
<When writing>
Value of internal data bus is output to these pins.
(2) When using 8-bit width as external data bus width:
Accessing external memory
<When reading>
Pins’ value is input into internal data bus. The value is input into low-order
internal data bus (DB
0
to DB
7
) when accessing an even address; it is input
into high-order internal data bus (DB
8
to DB
15
) when accessing an odd
address.
<When writing>
Value of internal data bus is output to these pins. The value of low-order
internal data bus (DB
0
to DB
7
) is output when accessing an even address;
the value of high-order internal data bus (DB
8
to DB
15
) is output when
accessing an odd address.
Accessing internal memory
<When reading>
These pins become high impedance.
<When writing>
Value of internal data bus is output to these pins.
When the external bus width is 8 bits, the mode where low-order address
(LA
0
to LA
7
) is output when RD or WR output is “H” and data (D
0
to D
7
) is
input/output when RD or WR output is “L” can be selected in specified
external memory area access cycle.
In single-chip mode, these pins have the same functions as port P0. In memory
expansion mode or microprocessor mode, these pins operate as follows:
(1) When using 16-bit width as external data bus width
Accessing external memory
<When reading>
The value is input into high-order internal data bus (DB
8
to DB
15
) when
accessing an odd address; these pins enter high impedance state when not
accessing an odd address.
<When writing>
Value of high-order internal data bus (DB
8
to DB
15
) is output to these pins.
Accessing internal memory
<When reading>
These pins enter high impedance state.
<When writing>
Value of internal data bus is output to these pins.
(2) When using 8-bit width as external data bus width
These pins become I/O port P11
