This information is preliminary.
This value is applicable if users do not delay configuration by extending the nCONFIG or nSTATUS low pulse
width.
The minimum and maximum numbers apply only if the internal oscillator is chosen as the clock source for starting
the device.

2 of the Configuration Handbook.
PS Configuration Using a Microprocessor
In the PS configuration scheme, a microprocessor can control the transfer
of configuration data from a storage device, such as flash memory, to the
target Cyclone III device.

information.
The MicroBlaster™ software driver enables you to configure Altera
FPGAs, including Cyclone III devices, through the ByteBlaster II or
ByteBlasterMV cable in PS mode. The MicroBlaster software driver
supports a RBF programming input file and is targeted for embedded PS
configuration. The source code is developed for the Windows NT
operating system. You can customize it to run on other operating systems.
