1. Minimum supply voltage without losing data stored in RAM (in Halt mode or under Reset) or in hardware registers (only in
Halt mode). Guaranteed by characterization, not tested in production.

1. The physical granularity of the memory is four bytes, so cycling is performed on four bytes even when a write/erase
operation addresses a single byte.
