    Hi everybody!

    I have following problem.:

    When powering on the STR711 from flash (flash empty) the initial state of the I/O Pin 0.11 differs from the I/O state when powering on from ram.

    That means if BOOT0=0 BOOT1=0 BOOTEN=1 (Flash), then P0.11 is low after powering on. And if BOOT0=0 BOOT1=1 BOOTEN=1 (RAM), then P0.11 is high after powering on.

    (Before executing or loading any code into RAM/Flash; - just power on)

    I want P0.11 high in both cases...

    Any hints?

    regards,

    Erwin
