Exit from asynchronous reset state
When the RSTIN pin is pulled high, the device restarts: as already mentioned, if internal
FLASH is used, the restarting occurs after the embedded FLASH initialization routine is
completed. The system configuration is latched from Port0: ALE, RD and WR/WRL pins are
driven to their inactive level. The device starts program execution from memory location
00'0000h in code segment 0. This starting location will typically point to the general
initialization routine. Timing of asynchronous Hardware Reset sequence are summarized in
Figure 26
This timing can be longer than Port0 settling time + PLL synchronization (if needed, that is
P0(15:13) changed).
It can longer than 500ns to take into account of Input Filter on
