当执行FRAMWrite_uint64((uint64_t *)FRAM_RECORD_ADDRESS,0); 时,后20*4会被修改为0
原来0xffffffff,0xffffffff,被改为0x0000ffff,0x00000000
当执行FRAMWrite_Long((uint32_t *)FRAM_RECORD_ADDRESS, 0);时,后10*4=40会被修改为0
原来0xffffffff,被改为0x0000ffff,
void FRAMWrite_uint64(uint64_t *pFRAM_write_ptr, uint64_t ui64data)
{
SYSCFG0 &= ~DFWP;
*pFRAM_write_ptr = ui64data;
SYSCFG0 |= DFWP;
}
void FRAMWrite_Long(uint32_t *pFRAM_write_ptr, uint32_t ui32data)
{
SYSCFG0 &= ~DFWP;
*pFRAM_write_ptr = ui32data;
SYSCFG0 |= DFWP;
}
#define FRAM_RECORD_ADDRESS 0x1812
FRAMWrite_uint64((uint64_t *)FRAM_RECORD_ADDRESS,0);
FRAMWrite_Long((uint32_t *)FRAM_RECORD_ADDRESS, 0);
