Configuration Specification  
Table 2–42 lists the internal clock frequency specification for the AS configuration  
scheme.

Notes to Table 2–42:  
(1) This applies to the DCLK frequency specification when using the internal oscillator as the configuration clock source.  
(2) The AS multi-device configuration scheme does not support DCLKfrequency of 100 MHz.  
PS Configuration Timing  
Figure 2–8 shows the timing waveform for a passive serial (PS) configuration when  
using a MAX II device or microprocessor as an external host.

Notes to Figure 2–8:  
(1) The beginning of this waveform shows the device in user mode. In user mode, nCONFIG  
, nSTATUS, and CONF_DONEare at logic high levels. When  
nCONFIGis pulled low, a reconfiguration cycle begins.  
(2) After power up, the Arria V device holds nSTATUSlow for the time of the POR delay.  
(3) After power up, before and during configuration, CONF_DONEis low.  
(4) Do not leave DCLKfloating after configuration. You can drive it high or low, whichever is more convenient.  
(5) DATA0is available as a user I/O pin after configuration. The state of this pin depends on the dual-purpose pin settings in the Device and Pins  
Option.  
(6) To ensure a successful configuration, send the entire configuration data to the Arria V device. CONF_DONEis released high after the Arria V device  
receives all the configuration data successfully. After CONF_DONEgoes high, send two additional falling edges on DCLKto begin initialization  
and enter user mode.  
(7) After the option bit to enable the INIT_DONEpin is configured into the device, the INIT_DONEgoes low.
