3, 4, 5 Multi-use pins, configurable as either LCD SEG driver or DIO.
(DIO4 = SCK, DIO5 = SDA when configured as EEPROM interface;
WPULSE = DIO6, VARPULSE = DIO7 when configured as pulse
outputs). If unused, these pins must be configured as DIOs and
set to outputs by the firmware.
3, 4, 5 Multi-use pins, configurable as either LCD SEG driver or SPI PORT.

pulled high) or LCD SEG drivers (when ICE_E tied to GND).
ICE enable. When zero, E_RST, E_TCLK and E_RXTX become
SEG32, SEG33 and SEG38 respectively. For production units, this
pin should be pulled to GND to disable the emulator port.

Multi-use pins, configurable as either multiplexer/clock output or LCD
segment driver using the I/O RAM registers CKOUT_E or
MUX_SYNC_E.
TMUXOUT

Digital output test multiplexer. Controlled by TMUX[3:0].
OPT_RX/DIO1
I/O
3, 4, 7 Multi-use pin, configurable as Optical Receive Input or general DIO.
When configured as OPT_RX, this pin receives a signal from an external
photo-detector used in an IR serial interface. If unused, this pin must
be terminated to V3P3D or GNDD, or configured as a DIO and set
to an output by the firmware.
OPT_TX/DIO2
I/O
3, 4
Multi-use pin, configurable as either optical LED transmit output,
WPULSE, RPULSE, or general DIO. When configured as OPT_TX,
this pin is capable of directly driving an LED for transmitting data in
an IR serial interface. If unused, this pin must be left open, or
configured as a DIO and set to an output by the firmware.
RESET
I
2
Chip reset: This input pin is used to reset the chip into a known state.
For normal operation, this pin is pulled low. To reset the chip, this pin
should be pulled high. This pin has an internal 30 μ A (nominal)
current source pull-down. No external reset circuitry is necessary.
RX
I
3
UART input. If this pin is unused, it must be terminated to V3P3D
or GNDD.
TX
TEST
O
I
4
7
UART output.
Enables Production Test. This pin must be grounded in normal
operation.
Pin types: P = Power, O = Output, I = Input, I/O = Input/Output.
The circuit number denotes the equivalent circuit, as specified in Section 5 I/O Equivalent Circuits.
