Page 2 - 16 Reset Port
Reset Port
This is a write-only port. You may write to this port when you wish to initiate
a board Reset. The write can consist of any value because the data is ignored.
The result of this write will be a hardware reset.
Whether or not the RF3880 adapter also resets the SCSI bus at this time is
determined by how you set a jumper on the board. (Information about the
configuration jumpers is in Chapter 3, Hardware Installation.)
To access the Reset Port use an offset of 18H from the base address of the
adapter (set by jumpers on the board).
When a reset has completed with no self-test errors, the RDY bit of the Status
Port will be set.
