RTS - Request to Send Control Output/Handshake Signal
RI - Ring Indicator Control Input. When remote wake-up is enabled in the internal
EEPROM taking RI# low (20ms active low pulse), this can be used to resume the PC
USB host controller from Suspend.
DSR - Data Set Ready Control Input/Handshake Signal
CTS - Clear To Send Control Input/Handshake Signal
PWREN -
RXLED -
connected to an LED.
EXTVCC - Use for applying main power (4.5 to 5.25 volts) to the module. Connect to
PORTVCC (Pin 9) if the module is to be powered by the USB port (typical configuration).
PORTVCC - Power from the USB port. Connect to EXTVCC (Pin 8) if the module is to
be powered by the USB port (typical configuration). 500mA is the maximum current
available to the USB adapter and target electronics if the USB device is configured for
high power.

Receive signaling output. Pulses low when receiving data via USB. This should be
(TTL level). For use with RS485 level converters.
PWREN# = 0: Normal operation.
PWREN# = 1: USB SUSPEND mode or device has not been configured.
This can be used by external circuitry to power down logic when device is in USB
suspend or has not been configured.

Active low power-enable output.
I
Transmit signaling output. Pulses low when transmitting data via USB. This should be
