Clock PLL output. Can be enabled and disabled by CKOUT_DIS.
Description
LCD Common Outputs: These 4 pins provide the select signals for the
LCD display.
Dedicated LCD Segment Output pins.
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 outputs.
Multi-use-pin LCD Segment Output/ MUX_SYNC is output for
Synchronous serial interface
Multi-use-pin, LCD Segment Outputs/ SRDY input for Synchronous
serial interface. When configured as SRDY, this pin must be pulled
down to GNDD.
Multi-use-pin, LCD Segment Output/ SFR output for Synchronous
serial interface.
Multi-use-pin, LCD Segment Output/ SDATA output for Synchronous
serial interface.
Multi-use-pin, LCD Segment Output/ SCLK output for Synchronous
serial interface.
Digital output test multiplexer. Controlled by DMUX[3:0].
Optical Receive Input: This pin may receive a signal from an external
photo-detector used in an IR serial interface. If this pin is unused it
must be terminated to V3P3D or GNDD.
Optical LED Transmit Output: This pin is designed to directly drive an
LED for transmitting data in an IR serial interface. Can be tristated with
OPT_TXDIS to be multiplexed with other DIO pins.
This input pin resets the chip into a known state. For normal operation,
this pin is set to 1. To reset the chip, this pin is driven to 0. This pin
has an internal 30µA (nominal) current source pull up. A 0.1µF ca-
pacitor to GNDD should be connected to this pin. See the precau-
tions in the Applications Section for terminating this pin.
UART input. The voltage applied at this input must be below 3.6V.
If this pin is unused it must be terminated to V3P3D or GNDD.
UART output.
Emulator serial data. This pin has an internal pull-up resistor.
Emulator clock.
Emulator reset. This pin has an internal pull-up resistor. See the
precautions in the Applications Section for terminating this pin.
Enables Production Test. This pin must be grounded in normal
operation.
