PIN DESCRIPTION

Pin	Name	Input/Output	Functions
VCC, VSS	Power supply		Supply 2.7 – 5.5 V to VCC and 0 V to VSS.
CNVSS	CNVSS input	Input	This pin controls the processor mode. Connect to VSS for single-chip mode, and
			to VCC for external ROM types.
______
RESET	Reset input	Input	To enter the reset state, this pin must be kept at a “L” condition which should be
			maintained for the required time.
XIN	Clock input	Input	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
XOUT	Clock output	Output	source should be connected to the XIN pin and the XOUT pin should be left open.
_
E	Enable output	Output	Data or instruction read and data write are performed when output from this pin
			is “L”.
BYTE	Bus width selection	Input	In memory expansion mode or microprocessor mode, this pin determines
	input		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.
AVCC,	Analog supply input		Power supply for the A-D converter. Connect AVCC to VCC and AVSS to VSS
AVSS			externally.
VREF	Reference voltage	Input	This is reference voltage input pin for the A-D converter.
	input
P00 – P07	I/O port P0	I/O	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.
P10 – P17	I/O port P1	I/O	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.
P20 – P27	I/O port P2	I/O	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”.
P30 – P33	I/O port P3	I/O	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.
P40 – P47	I/O port P4	I/O	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.
P50 – P57	I/O port P5	I/O	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.
P60 – P67	I/O port P6	I/O	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.
P70 – P77	I/O port P7	I/O	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.
P80 – P87	I/O port P8	I/O	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.

BASIC FUNCTION BLOCKS

The M37702M2LXXXGP has the same functions as the M37702M2BXXXFP except for the reset circuit.

Refer to the section on the M37702M2BXXXFP.

Figure 1 shows the status of the internal registers when a reset occurs.

Figure 2 shows an example of a reset circuit. The reset input voltage must be held 0.55 V or lower when the power voltage reaches 2.7 V.

RESET CIRCUIT

______

Reset occurs when the RESET pin is returned to “H” level after holding it at “L” level when the power voltage is at 2.7 – 5.5 V. Program execution starts at the address formed by setting the address pins A23 – A16 to 0016, A15 – A8 to the contents of address FFFF16, and A7 – A0 to the contents of address FFFE16.
