CFDETECT
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
5
DATABUFRDY
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
reading from the CompactFlash controller or into the buffer when writing to the
CompactFlash or Configuration controller
6
DATABUFMODE
Data buffer mode status:
0 means read-only mode
1 means write-only mode
7
CFGDONE
Configuration DONE status:
0 means that the configuration process has not completed
1 means that the entire System ACE CF controller configuration file has been
executed and configuration of all devices in the target Boundary-Scan chain is
complete
8
RDYFORCFCMD
Ready for CompactFlash controller command:
0 means not ready for command
1 means ready for command
9
CFGMODEPIN
Configuration mode pin (note that this can be overridden by the CFGMODE bit in the
CONTROLREG register):
1 means automatically start the configuration process immediately after System ACE
CF controller Reset
0 means wait for CFGSTART bit in CONTROLREG before starting the configuration
process

CFGADDRPIN0
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)

CFBSY
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
accessed; Bits 18-23 of the STATUSREG register are not valid when this bit is set to 1
18
CFRDY
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
19
CFDWF
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
