TMDSIDK437X: L3 memory map

Part Number: TMDSIDK437X

Hello.

In Technical reference manual  (SPRUHL7I–April 2014–Revised December 2019), chapter 2.1 L3 Memory Map, I'm not so clear understand this:

QSPI 0x3000_0000 0x33FF_FFFF 64MB QSPI CS0 Maddrspace 1 space

Does this mean that the peripheral registers of the SPI module occupy 64 MB of internal memory?

or for examle this:

ADC1 0x5480_0000 0x54BF_FFFF 4MB ADC1 DMA Port

Does this mean that the peripheral registers of the ADC module occupy 4 MB of internal memory?

What kind of addresses does table L3 describe?

    No, this is the QSPI memory addressable space. See section 27.3.4 for details.

    No, ADC1 registers start at 0x4834_C000 and use 8kB of memory space. See section 12.3.3.2 for details od ADC1 DMA port.
