Version 1.5

8-Bit Micro-Controller

Bit-6 of Port 3

PT3_6

PT3_5

PT3_4

I/O

This is a programmable pin for general-purpose I/O Port 3. The driving current

and pull-high or pull-low can be selected by user register.

Bit-5 of Port 3

This is a programmable pin for general-purpose I/O Port 3. The driving current

and pull-high or pull-low can be selected by user register.

Bit-4 of Port 3

This is a programmable pin for general-purpose I/O Port 3. The driving current

and pull-high or pull-low can be selected by user register.

Bit-3 of Port 3

PT3_3

I/O

The PT3_3 is also as the transmission output of user’s UART. In UART mode,

the pin is always output except the power saving mode.

Bit-2 of Port 3

PT3_2

The PT3_2 is also as the receive input of user’s UART. In UART mode, the pin

is always input.

Bit-1 of Port 3

PT3_1

LCD_E

PT3_0

LCD_RW

The PT3_1 is also as the chip enable of external LCD controller. If the external

LCD enabled, the pin is always output except the power saving mode.

Bit-0 of Port 3

The PT3_0 is also as the read/write signal of external LCD controller. If the

external LCD enabled, the pin is always output except the power saving mode.

Bit 7~0 of Port 4

PT4_[7:0]

IOUT

I/O

This is a programmable pin for general-purpose I/O Port 4. The driving current

and pull-high or pull-low can be selected by user register.

DAC Current Output

OUT

This pin is the current output of DAC.

ADC Analog Input

These pins are the analog input of 10-bit ADC for 4-channel.

ADC Mode

Touch Panel Mode

AIN[3~0]

--------------------------------------------------

AIN0

AIN1

AIN2

AIN3

14-bit Address Bus.

These signal are used for external memory address bus.

8-bit Data Bus.

These signal are used for external memory data bus.

Flash Chip Select, active low.

ADDR[13:0]

D[7:0]

OUT

I/O

FL_CE#

OUT

This signal is used for external flash.

Flash Write Enable, active low.

This signal is used for external flash.

If REG[1032h] bit6 is set as 1, and then FL_WE# and MEM_WE can be jointly

used.

FL_WE#

FL_OE#

OUT

Flash Output Enable, active low.

This signal is used for external flash.

If REG[1032h] bit6 is set as 1, and then FL_OE# and MEM_OE# can be jointly

used.
