Description
Active low. Media eject requested. If remote
wakeup is enabled by the USB host, a state
change on this pin will cause the ISD-300A1 to
perform a USB remote wakeup event. Filtered
internally by ISD-300A1. Set NEJECT = 1 if the
functionality is not utilized.

This pin may be left as a no-connect pin if the I
interface is not utilized.

for correct operation in all ISD-300A1 modes of
operation.

Active high. ATA IORDY pull-up connection.
Driven low during USB suspend, 3-stated (hi-Z)
when ATA_EN=0.
Active low. ATA DMARQ pull-down
connection. 3-state (hi-Z) when ATA_EN=0.
Active low. ATA reset.
Active low. LED drive to indicate USB bus
speed. Active when utilizing HS, inactive during
FS or USB suspend or other low power modes of
operation. Open drain during normal operation.
Leave as a no-connect pin if functionality is not
utilized.
Active low. LED drive to indicate status of
device initialization. Flashing when initializing is
in progress, solid when the device is initialized,
and inactive during USB suspend or other low
power modes of operation. Open drain during
normal modes of operation. Leave as a no-
connect pin if functionality is not utilized.
Active high. Indicates ISD-300A1 configuration /
USB descriptor information is obtained using the
ATA vendor specific Identify command (FBh)
USB full speed output buffer (D−). RSDM also
functions as a current sink for termination during
HS operation.
