Internal flash on RT 1064 ?

[carstengroen]

I have the EVK 1064 which runs just fine. I'm in the process of designing my first board with the RT 1064, and in that process I have a hard time finding info on the internal (QSPI?) Flash. On the EVK, I have the Flash at 0x70000000 and according to the UM this is FlexSPI2 interface. Is that connected to the internal flash of the CPU, or is this the external flash (on the EVK) ?

What pins on the CPU is used (I assume that some of the pins are connected both to external pins as well as the internal Flash chip) ?

I have not (yet) been able to find info on the internal flash in the manuals so far...
