*** Using Compiler 'V5.06 update 6 (build 750)', folder: 'D:\Keil_5\MDK5\ARM\ARMCC\Bin'compiling main.c...

GPIOB_CRL &= ~(0x0F<<(4*5));
User\main.c: 1 warning, 2 errors
"User\main.c" - 2 Error(s), 1 Warning(s).
我按照教程敲的,请问这个错误是什么原因。
代码:
#include "stm32f10x.h"
void SystemInit(void)
{
}
int main()
{
RCC_APB2ENR |= 1<<3;
GPIOB_CRL &= ~(0x0F<<(4*5));
GPIOB_CRL |= (3<<4*5);
GPIOB_BSRR = (1<<(16+5));
while(1)
{
}
}
