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
Table 8.1 232 UART mode the IO signal lines Description
**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.
