CRP3 and user code invalid

I noticed in the user manual that the LPC1317 uC will enter in ISP mode if the user code is invalid and the code protection is CRP3.  However,  I don't see in the document which ISP commands are available in that mode. 


The table 345 in the user manual mentions the CRP3 as N/A for all ISP commands. But there is no description in that table if the user code is invalid (i.e. the vector is corrupted)...  I'd like to know the list the ISP is available in CRP3 mode.
