OUTPUT
When high, do not read data from the FIFO. When low,
there is data available in the FIFO which can be read by
strobing RD# low then high again ** Note 18

TXE#
OUTPUT
When high, do not write data into the FIFO. When low,
data can be written into the FIFO by strobing WR high
then low. ** Note 18

RD#
INPUT
Enables Current FIFO Data Byte on D0..D7 when low.
Fetches the next FIFO Data Byte (if available) from the
Receive FIFO Buffer when RD# goes from low to high.
** Note 17

WR
INPUT
Writes the Data Byte on the D0..D7 into the Transmit
FIFO Buffer when WR goes from high to low.

SI/WU
INPUT
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 8.3 FIFO Control Interface Group
**Note 17: In Input Mode, these pins are pulled to VCCIO via internal 200K resistors. These can be
programmed to gently pull low during USB suspend (PWREN# = “1” ) by setting this option in the
EEPROM.
**Note 18: During device reset, these pins are tri-state but pulled up to VCCIO via internal 200K
resistors.
