Read: Anytime
Write: Writes have no effect
Reset: Defined at chip integration, see device overview section.
The MEMSIZ1 register reflects the state of the FLASH or ROM physical memory space and paging
switches at the core boundary which are configured at system integration. This register allows read
visibility to the state of these switches.

The RAM Reset BASE Address is based on the reset value of the INITRM register, 0x0009.
Alignment of the Allocated RAM space within the RAM mappable region is dependent on the value of RAMHAL.

As stated, the bits in this register provide read visibility to the system
physical memory space allocations defined at system integration. The actual
array size for any given type of memory block may differ from the allocated
size. Please refer to the device overview chapter for actual sizes.
