Subject: [PATCH 06/13] dev_table.c: Add STM32H7A3xx/B3xx (Device ID 0x480)
RM0455 rev 6: (STM32H7A3/7B3 and STM32H7B0 Value line)
Table 12. Flash memory organization (STM32H7A3xI/7B3xI devices)
Section 4.3.4:
"The embedded Flash non-volatile memory is composed of:
- For STM32H7B3xx and STM32H7A3xI devices: a 2-Mbyte main memory block,
organized as two banks of 1 Mbyte each.
- For STM32H7A3xG devices: a 1-Mbyte main memory block, organized as two
banks of 512 Kbyte each."
"Each bank is in turn divided in up to 128 sectors of 8 Kbytes each"
(untested)
