(4) Ports

- Input/output ports: 6 ports (48 terminals)

I/O programmable in nibble units:

1 port (8 terminals)

I/O programmable for each bit individually: 5 ports (40 terminals)

- Input port: 1 port (4 terminals)

- LCD drive common output ports:

32 terminals/16 terminals (switched by mask option)

- LCD drive segment output ports:

32 terminals/48 terminals (switched by mask option)

(5) External Program Memory Access Function

- Ports

1. Data input/output: 1 port (8 terminals)

2. Address output:

2 ports (16 terminals)

3. Bank address output: Use normal I/O ports as bank address output by program control.

- External program memory access function

External program memory space: 64K bytes

Internal/external program can be switched by program. (at initial: internal program operation mode)

Enabling/disabling of switching from external program to internal program is provided.

- External data memory access function

By LDC instruction execution:

External data memory space: 64K bytes (Use normal I/O ports as bank address output by program control.)

1. When internal program is operating:

Access to the internal or external ROM data is selectable by program.

2. When external program is operating:

Only the external ROM data can be accessed.

(Only the external program memory space (64K bytes) can be referred.)

- External RAM memory access function (Able to be used when internal program is executed)

By LDX instruction/STX instruction execution:

External RAM space: 64K bytes (Use normal I/O ports as bank address output by program control.)

(When using the external RAM space in the external program operation mode, refer to the “LC868364 User’s Manual”

for details.)

(6) LCD Automatic Display Controller/Common Driver/Segment Driver

- Display duty:

1/32 duty, 1/16 duty

- Display bias:

1/5, 1/7 bias

- Graphic display

A maximum of 1,024 dots capability (without external segment driver)

32 × 80 dots display capability per each segment driver (LC868920A) can be expanded, when 1/32 duty is selected.

Note: If the display capability is expanded by the LC86920A when 1/16 duty is selected, only S1-S32 of the LC868364A can be

used, and S33-S48 can not be used. (Refer to the LC868920A specification sheet.)
