lpc54606 internal flash and deep sleep mode

Dows LPC54606 have a dependency on External flash to go into Deep Sleep mode? I have a LPC54606 board and we use internal flash for code execution. We can enter and exit sleep mode, but we cannot exit deep sleep at all. But on the LPC54628 board deep sleep entry and exit seems to be working fine. Documentation says flash goes into standby in deep sleep - i am not sure whether it affects code execution when exiting deep sleep. The LPC543628 dev board from what i understand uses external flash (WinBond). 

 

Would appreciate any pointers on this issue, 

 

Thanks
