8.13.5.14 Incorrect Access Report

When an access is performed in a register, the type of access is verified against the type of the register being accessed. As example, a read access to a register declared as write-only is abnormal. A write access to a register declared as read-only is also abnormal.

Read or write accesses to undefined addresses are also reported.

The flag PUF_WPSR.SWE=1 when an abnormal access is detected and the type of abnormal access is provided in PUF_WPSR.

The flag PUF_ASISR.SECE=1 when an abnormal access is detected. When PUF_ASIER.SECE=1, an interrupt is triggered.
