Note:
Required assertion time of HRESET to activate reset flow
Required assertion time of PORESET with stable clock applied to CLKIN when
the device is in PCI host mode
Required assertion time of PORESET with stable clock applied to PCI_CLK when
the device is in PCI agent mode
HRESET assertion (output)
HRESET negation to negation (output)
Input setup time for POR config signals (CFG_RESET_SOURCE[0:3],
CFG_CLKIN_DIV, and CFG_LBMUX) with respect to negation of PORESET
when the device is in PCI host mode
Input setup time for POR config signals (CFG_RESET_SOURCE[0:3],
CFG_CLKIN_DIV, and CFG_LBMUX) with respect to negation of PORESET
when the device is in PCI agent mode
Input hold time for POR config signals with respect to negation of HRESET
• HRESET and SRESET are open drain pin, thus V
• This table applies for pins PORESET and HRESET. The PORESET is input pin, thus stated output voltages are not relevant.
RESET Initialization
