CC2640: Are all readonly code and data downloaded to flash?

Part Number: CC2640

Hello,

From the datasheet,

"Placing Drivers, Bluetooth® Low Energy Controller, and Bootloader in ROM"

For example, if the iar map file information of the app and stack projects are like below,

does it mean that all readonly code and data (49211+4690+68066+8773) will be downloaded to the flash or,

part of readonly code and data could be downloaded to the ROM?

(I'm using FLASH_ROM_BUILD=1 in the stack project and RTOS_ROM=1 in the app project)

app
49 211 bytes of readonly code memory
4 690 bytes of readonly data memory
10 806 bytes of readwrite data memory (+ 16 384 absolute)

stack
68 066 bytes of readonly code memory
8 773 bytes of readonly data memory
1 712 bytes of readwrite data memory

Thanks,

Calvin
