Hello

STM32L0 CUBE pack, file stm32l0xx_hal_gpio.c have a mega-bug. When will be used GPIO EXTI function, at end of config the all SYSCFG->EXTICR registers will be set to FFFF.

in file, function HAL_GPIO_Init:

259: temp &= ~((uint32_t)0x0F) << (4 * (position & 0x03));

must be:

259: temp &= ~(((uint32_t)0x0F) << (4 * (position & 0x03)));

This bug may have place in the other packs, need to check it.

To developers: People, please adjust it in your sources and archives!!!
