MPU Address Status Register 1 (MPUASTAT1)
Access violation address bits — The ADDR[22:16] bits contain bits [22:16] of the global address which
caused the current access violation interrupt. These bits are undefined if the access error flag bit (AEF) in the
MPUFLG register is not set.
Access violation address bits — The ADDR[15:8] bits contain bits [15:8] of the global address which caused
the current access violation interrupt. These bits are undefined if the access error flag bit (AEF) in the MPUFLG
register is not set.
