Asynchronous Peripheral Mode Programming Switching Characteristics
A Low on the PROGRAM input is the more radical ap-
proach, and is recommended when the power-supply rise
time is excessive or poorly defined. As long as PROGRAM
is Low, the XC4000 device keeps clearing its configuration
memory. When PROGRAM goes High, the configuration
memory is cleared one more time, followed by the begin-
ning of configuration, provided the INIT input is not exter-
nally held Low. Note that a Low on the PROGRAM input
automatically forces a Low on the INIT output.

1. Configuration must be delayed until the INIT of all LCA devices is High.
2. Time from end of WS to CCLK cycle for the new byte of data depends on completion of previous byte processing and
3. CCLK and DOUT timing is tested in slave mode.
4. T
Data need not be held beyond the rising edge of WS. BUSY will go active within 60 ns after the end of WS.
The shortest T

the phase of the internal timing generator for CCLK.
BUSY
indicates that the double-buffered parallel-to-serial converter is not yet ready to receive new data.

Using an open-collector or open-drain driver to hold INIT
Low before the beginning of configuration, causes the LCA
device to wait after having completed the configuration
memory clear operation. When INIT is no longer held Low
externally, the device determines its configuration mode
by capturing its status inputs, and is ready to start the
configuration process. A master device waits an additional
max 250 s to make sure that all slaves in the potential
daisy-chain have seen INIT being High.
