Yees!

I edit startup.a51 and instead:

                CSEG    AT      0
?C_STARTUP:     LJMP    STARTUP1

I add at beginning ANL 0xD9,#0xBF so:

                CSEG    AT      0
?C_STARTUP:     ;PCA0MD &= ~0x40;                    // WDTE = 0 (clear watchdog timer enable)
               ANL     0xD9,#0xBF
               LJMP    STARTUP1

and work OK also on silab toolstick debug adapter!!
THANKS for helping me!
