Functions
Supply 2.7 – 5.5 V to VCC and 0 V to VSS.
This pin controls the processor mode. Connect to VSS for single-chip mode, and
to VCC for external ROM types.
To enter the reset state, this pin must be kept at a “L” condition which should be
maintained for the required time.
These are I/O pins of internal clock generating circuit. Connect a ceramic or quartz
crystal resonator between XIN and XOUT. When an external clock is used, the clock
source should be connected to the XIN pin and the XOUT pin should be left open.
Data or instruction read and data write are performed when output from this pin
is “L”.
In memory expansion mode or microprocessor mode, this pin determines
whether the external data bus is 8-bit width or 16-bit width. The width is 16 bits
when “L” signal inputs and 8 bits when “H” signal inputs.
Power supply for the A-D converter. Connect AVCC to VCC and AVSS to VSS
externally.
This is reference voltage input pin for the A-D converter.
In single-chip mode, port P0 becomes an 8-bit I/O port. An I/O direction register
is available so that each pin can be programmed for input or output. These ports
are in input mode when reset.
Address (A7 – A0) is output in memory expansion mode or microprocessor mode.
In single-chip mode, these pins have the same functions as port P0. When the
BYTE pin is set to “L” in memory expansion mode or microprocessor mode and
external data bus is 16-bit width, high-order data (D15 – D8) is input or output
__
when E output is “L” and an address (A15 – A8) is output when E output is “H”.
If the BYTE pin is “H” that is an external data bus is 8-bit width, only address
(A15 – A8) is output.
In single-chip mode, these pins have the same functions as port P0. In memory
expansion mode or microprocessor mode low-order data (D7 – D0) is input or
__
output when E output is “L” and an address (A23 – A16) is output when E output
is “H”.
In single-chip mode, these pins have the same functions as port P0. In memory
__
____
_____
expansion mode or microprocessor mode, R/W, BHE, ALE and HLDA signals
are output.
In single-chip mode, these pins have the same functions as port P0. In memory
_____
____
expansion mode or microprocessor mode, P40 and P41 become HOLD and RDY
input pin respectively. Functions of other pins are the same as in single-chip
mode. In single-chip mode or memory expansion mode, port P42 can be pro-
grammed for
φ1 output pin divided the clock to XIN pin by 2. In microprocessor
mode. P42 always has the function as
φ1 output pin.
In addition to having the same functions as port P0 in single-chip mode, these
pins also function as I/O pins for timer A0, timer A1, timer A2 and timer A3.
In addition to having the same functions as port P0 in single-chip mode, these
____ ____
pins also function as I/O pins for timer A4, external interrupt input INT0, INT1 and
____
INT2 pins, and input pins for timer B0, timer B1 and timer B2.
In addition to having the same functions as port P0 in single-chip mode, these
pins also function as analog input AN0 – AN7 input pins. P77 also has an A-D
conversion trigger input function.
In addition to having the same functions as port P0 in single-chip mode, these
____ ____
pins also function as RXD, TXD, CLK, CTS/RTS pins for UART 0 and UART 1.
