SEG32, SEG33 and SEG38 respectively. For production units, this
pin should be pulled to GND to disable the emulator port.

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 this pin is unused it
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.
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 μA (nominal) current
source pull-down. No external reset circuitry is necessary.
