I'm using GPIO pins to fire a Thyristor. When the MCU boots, the GPIO's which I have used for firing gets low due to which I have output which is unwanted. When the flash booting is over the GPIO's gets SET (high state) for which it is programmed and low when required to obtain required output.
The GPIO's used are: 40, 55, 11, 54, 44 and 8
Please suggest me how should I keep these at high state when MCU boots. I have tried external pull ups (10K ohm), it didn't help.
