is enabled in the EEPROM, taking RI# low can be used to
resume the PC USB Host controller from suspend.

Enable Transmit Data for RS485
Goes low during USB Suspend Mode. Typically used to power-
down an external TTL to RS232 level converter I.C. in USB to
RS232 converter designs.
LED Drive - Pulses Low when Transmitting Data via USB.
LED Drive - Pulses Low when Receiving Data via USB.
The Send Immediate / WakeUp signal combines two functions
on a single pin. If USB is in suspend mode (PWREN# = 1) and
remote wakeup is enabled in the EEPROM , strobing this pin
low will cause the device to request a resume on the USB Bus.
Normally, this can be used to wake up the Host PC.
During normal operation (PWREN# = 0), if this pin is strobed low
any data in the device TX buffer will be sent out over USB on the
next Bulk-IN request from the drivers regardless of the pending
packet size. This can be used to optimise USB transfer speed for
some applications. Tie this pin to VCCIO if not used.

**Note 16 :
These pins are pulled to up VCCIO via internal 200K resistors during Reset and USB Suspend mode.
These can be programmed to gently pull low during USB suspend ( PWREN# = “1” ) by setting this option in the
EEPROM.
