pub fn mcu_invalidate_range(start: u32, len: u32)Expand description
Invalidate the CPU data cache for [start, start + len). Equivalent of
LL_ATON_Cache_MCU_Invalidate_Range. Call after the NPU writes an output
buffer and before the CPU reads it.
start/len should be 32-byte aligned; unaligned edges are cleaned and
invalidated to avoid corrupting neighbouring data.
