The number of data bytes written to the “data” field in the
Output FIFO Data Register (p.
Indicates whether the host CPU(READ side) or IDT88K8483 (WRITE side) has con-
trol of OFIFO.
0: IDT88K8483 (WRITE side) has control of IFIFO.
1: Host CPU(READ side) has control of IFIFO.
This flag indicates whether the chip is ready to download the firmware binary file
from the host CPU. This flag is checked before the host CPU downloads to the
IDT88K8483. This bit is cleared by reset and will go high after the chip is initialized.
0:Not ready for download.
1:Ready for application s/w download.
This flag indicates whether the downloading procedure is finished.
0:Download taking place.
1:Download finished.
This bit indicates that the downloaded software has initiated the chip and user can
access it. This bit is set by downloaded software and is cleared by reset.
0:Chip not yet ready.
1:Chip is ready to be used.
