Este es mi código:
#include "stm32f10x.h"
#include "core_cm3.h"
#include "custom.h"
//#include "LCD-HD44780.h"
//int i;
int main(void)
{
RCC->APB2ENR |= BIT3;
GPIOB->CRH |= BIT0 || BIT1;
GPIOB->CRH &= ~BIT2 && ~BIT3;
GPIOB->BSRR |= BIT8;
GPIOB->CRH |= BIT4 || BIT5;
GPIOB->CRH &= ~BIT6 && ~BIT7;
GPIOB->BSRR |= BIT9;
while (1)
{
}
}

El LED en el Pin 8 se enciende Pero en el Pin 9 no se enciende. Y este todo el código que escribí. No puedo averiguar dónde está el problema.
