CompactFlash detect flag:
• 0 means that no CompactFlash device is connected to the System ACE CF controller
• 1 means that a CompactFlash is connected to the System ACE CF controller
Data buffer ready status:
• 0 means that the data buffer is not ready for data transfer
• 1 means that the data buffer is ready for data to be transferred out of the buffer when
Data buffer mode status:
• 0 means read-only mode
• 1 means write-only mode

Reserved
Configuration address pins that are used as an offset into the system configuration file in
the CompactFlash device used to locate the System ACE CF controller configuration data
file (note that these pins can be overridden by the contents of the CFGADDRBIT[2:0] of
the CONTROLREG register)
Reserved
CompactFlash BUSY bit (reflects the state of the BSY bit in the status register of the
CompactFlash device):
• 0 means that the CompactFlash device is not busy
• 1 means that the CompactFlash command register and data buffer cannot be
CompactFlash ready for operation bit (reflects the state of the RDY bit in the status register
of the CompactFlash device):
• 0 means the CompactFlash device is NOT ready to accept commands
• 1 means CompactFlash device is ready to accept commands
CompactFlash data write fault bit (reflects the state of the DWF bit in the status register of
the CompactFlash device):
• 0 means that a write fault has NOT occurred
• 1 means that a write fault has occurred
reading from the CompactFlash controller or into the buffer when writing to the
