Freescale Semiconductor
Required assertion time of HRESET (input) to activate reset flow
Required assertion time of PORESET with stable power and clock applied to
SYS_CLK_IN
HRESET assertion (output)
Input setup time for POR configuration signals (CFG_RESET_SOURCE[0:3]) with
respect to negation of PORESET
Input hold time for POR configuration signals with respect to negation of HRESET
Time for the device to turn off POR configuration signal drivers with respect to the
assertion of HRESET
