R
Name
Forces the CompactFlash arbitration logic to grant a lock to the MPU interface based on
the value of the LOCKREQ bit of the CONTROLREG register (default is 0):
• 0 means do not force MPU lock request (i.e., arbitrate between Configuration
• 1 means force MPU lock request (i.e., do not perform arbitration: grant lock request
CF arbitration lock request signal; Once a lock is granted, the LOCKREQ must be
de-asserted before the lock is removed (default is 0):
• 0 means do not request CompactFlash access lock
• 1 means request CompactFlash access lock
Forces the overriding of the CFGADDR(1:0) pins in favor of using the CFGADDRBIT(2:0)
bits of the CONTROLREG(15:13) register (default is 0):
• 0 means use the CFGADDR(1:0) pins
• 1 means use the CONTROLREG(15:13) register bits
Forces the overriding of CFGMODEPIN in favor of using the CFGMODE bit of the
CONTROLREG register (default is 0):
• 0 means use CFGMODEPIN
• 1 means use the CFGMODE bit of the CONTROLREG register
Configuration mode (default is 0):
• 1 means automatically start the configuration process immediately after System ACE CF
• 0 means wait for CFGSTART bit in CONTROLREG before starting the configuration
Configuration start bit (default is 0):
• 0 means do not start configuration
• 1 means start configuration process
Configuration select (default is 0):
• 0 means configure from CompactFlash
• 1 means configure from MPU interface
Configuration/CompactFlash controller reset (default is 0):
• 0 means do not reset
• 1 means reset the Configuration and CompactFlash controllers (this also causes a
Data buffer ready IRQ enable (default is 0):
• 1 means interrupts are enabled for when data buffer is ready for transfer of data into or
• 0 means data buffer ready interrupts are disabled
Error IRQ enable (default is 0):
• 1 means interrupts are enabled for when an error occurs
• 0 means error interrupts are disabled
