Apply 5 V±0.5 V to Vcc, and 0 V to Vss.
This pin controls the processor mode. Connect this pin to VSS for the single-chip
mode or memory expansion mode, and VCC for the microprocessor mode.
Connect this pin to Vss.
The microcomputer is reset when “L” level is applied to this pin.
These are input and output pins of the internal clock generating circuit. Connect a
ceramic or quartz- crystal resonator between the XIN and XOUT pins. When an
external clock is used, the clock source should be connected to the XIN pin, and the
XOUT pin should be left open.
This pin determines whether the external data bus has an 8-bit width or 16-bit width
for the memory expansion mode or microprocessor mode. The width is 16 bits when
“L” signal is input, and 8 bits when “H” signal is input. When BYTE = Vss level, by
the register setting, the external data bus for each of areas CS1 to CS3 can have a
width of 8 bits.
When using the PLL frequency multiplier, connect this pin to the filter circuit. When
not using, this pin should be left open.
Power supply input pins for the A-D converter and the D-A converter. Connect AVcc
to Vcc, and AVss to Vss externally.
This is the reference voltage input pin for the A-D converter and the D-A converter.
s In single-chip mode
Port P0 is an 8-bit I/O port. This port has an I/O direction register, and each pin
can be programmed for input or output. These pins enter the input mode at
reset.
s In memory expansion and microprocessor modes
Address (A16–A23) is output. These pins also function as I/O port pins according
to the register setting.
s In single-chip mode
These pins have the same functions as port P0.
s In memory expansion and microprocessor modes
The low-order 8 bits of data (D0–D7) are input/output. When the external data bus
has an 8-bit width, address (LA0–LA7) output and data (D0–D7) input/output can
be performed with the time-sharing method, according to the register setting.
s In single-chip mode or When 8-bit external data bus is used in memory expansion
mode and microprocessor mode
These pins have the same functions as port P0.
s When the 16-bit external data bus is used in memory expansion or microproce-
ssor mode
The high-order 8 bits of data (D8–D15) are input or output.
s In single-chip mode
These pins have the same functions as port P0.
s In memory expansion mode
P30 functions as an I/O port pin; and P31, P32, and P33 function as the output
pins of RD, BLW, BHW, respectively. P30 also functions as an output pin of RDY
according to the register setting. When the external data bus has a width of 8 bits,
the BHW pin functions as an I/O port pin (P33).
s In microprocessor mode
P30 functions as an input pin of RDY; and P31,P32, P33 function as the output
pins of RD, BLW, BHW, respectively. P30 also functions as an I/O port pin accord-
ing to the register setting. When the external data bus has a width of 8 bits,
the BHW pin functions as an I/O port pin (P33).
s In single-chip mode
These pins have the same functions as port P0.
s In memory expansion mode
P40–P47 function as I/O port pins. According to the register setting, these pins
function as output pins or input pins of ALE,
φ1, HLDA, HOLD, CS0–CS3, respec-
tively.
s In microprocessor mode
P40–P44 function as output or input pins of ALE,
φ1, HLDA, HOLD, CS0, and
P45–P47 as I/O port pins, respectively. According to the register setting, P40–P43
also function as I/O port pins, and P45–P47 as output pins of CS1–CS3.
