variant usage

[burrbull]

Looks like you've found a hole in svd2rust API safety.

esp-hal/esp-hal/src/assist_debug.rs

Line 44 in 1846543

.write(|w| w.core_0_sp_min().variant(lower_bound));

This seems unrelated to the HAL so I am going to close it. If I am mistaken please feel free to add more information and reopon.

variant should not be used for writing raw bytes. There is bits for this. Safe or unsually unsafe depending on writeConstrains values.
This is a hole that variant is possible to use there.
Trying to fix it with rust-embedded/svd2rust#825
