请问是在下面的代码中加入自己的密码吗，这个函数没有找到调用的地方，会执行吗

//
// CsmUnlock - This function unlocks the CSM. User must replace 0xFFFF's with
// current password for the DSP. Returns 1 if unlock is successful.
//
Uint16 CsmUnlock(void)
{
volatile Uint16 temp;

//
// Load the key registers with the current password. The 0xFFFF's are dummy
// passwords. User should replace them with the correct password for the
// DSP.
//
EALLOW;
DcsmZ1Regs.Z1_CSMKEY0 = 0xFFFFFFFF;
DcsmZ1Regs.Z1_CSMKEY1 = 0xFFFFFFFF;
DcsmZ1Regs.Z1_CSMKEY2 = 0xFFFFFFFF;
DcsmZ1Regs.Z1_CSMKEY3 = 0xFFFFFFFF;

DcsmZ2Regs.Z2_CSMKEY0 = 0xFFFFFFFF;
DcsmZ2Regs.Z2_CSMKEY1 = 0xFFFFFFFF;
DcsmZ2Regs.Z2_CSMKEY2 = 0xFFFFFFFF;
DcsmZ2Regs.Z2_CSMKEY3 = 0xFFFFFFFF;
EDIS;

return(0);
