Description
LCD Common Outputs: These 4 pins provide the select signals for the LCD display.
Dedicated LCD Segment Output.
Multi-use pins, configurable as either LCD SEG driver or DIO. (DIO4 = SCK, DIO5 =
SDA when configured as EEPROM interface, WPULSE = DIO6 when configured as
pulse outputs). If unused, these pins must be configured as outputs.
Multi-use pins, configurable as either LCD SEG driver or DIO. If unused, these
pins must be configured as outputs.
Multi-use pins, configurable as either emulator port pins (when ICE_E 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. This pin should be brought out to the programming inter-
face in order to create a way for reprogramming parts that have the SECURE bit set.

Digital output test multiplexer. Controlled by TMUX [4:0].
Multi-use pin, configurable as either 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 configured as an
output or terminated to V3P3D or GNDD.
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 configured as an output or terminated to V3P3D or GNDD.
This input pin resets the chip into a known state. For normal operation, this pin is
