Lpc2000

Hi all,

   I am using LPC2136 IAP and gone through following important 
sentense, 

1.The IAP routine resides at 0x7FFF FFF0 location and it is thumb
code.

2.The flash memory is not accessible during a write or erase 
operation. IAP commands,
which results in a flash write/erase operation, use 32 bytes of 
space in the top portion of
the on-chip RAM for execution.

From Memory mapped of LPC21XX it shows that at adress 0x7FFF FFF0 
there is BOOT BLOCK REMAPPED FROM ON-CHIP FLASH MEMORY.

  Is this the same area where IAP routine reside?
  

Thanks & regards,s
