The ADC region size is 256B, split as:
- [0x00 - 0x4f] defined
- [0x50 - 0xff] reserved
All registers are 32-bit (thus when the datasheet mentions the
last defined register is 0x4c, it means its address range is
0x4c .. 0x4f.
This model implementation is also 32-bit. Set MemoryRegionOps
'impl' fields.
See:
'RM0033 Reference manual Rev 8', Table 10.13.18 "ADC register map".
