How to access the ISP-AP of LPC5411x?

Hi,

I have got a lot of information about ISP-AP from the LPC5411x user manual. Then I want to try to access the ISP-AP,  say read/write the registers of the ISP-AP. But I have no idea how to write a command into ISP-AP by a debugger. Is there any utility to facilitate the practice? Or what's the best practice?

Thanks a lot.

I have read the ID register of ISP-AP by both redlink sever command and run-time memory access. Both results show the value of this register is  0x0 instead of 0x002A0000 which shown in the LPC5411x user manual. So the further doubt is that whether the ISP-AP exists on the LPC54114.
