The Write Protection has blocked a Write access to a protected register (since the last read).
Software Reset has been performed while Write Protection was enabled (since the last read
or since the last write access on MR, IER, IDR or CSRx).
Both Write Protection violation and software reset with Write Protection enabled have
occurred since the last read.
Write accesses have been detected on MR (while a chip select was active) or on CSRi (while
the Chip Select “i” was active) since the last read.
The Write Protection has blocked a Write access to a protected register and write accesses
have been detected on MR (while a chip select was active) or on CSRi (while the Chip Select
“i” was active) since the last read.
Software Reset has been performed while Write Protection was enabled (since the last read
or since the last write access on MR, IER, IDR or CSRx) and some write accesses have been
detected on MR (while a chip select was active) or on CSRi (while the Chip Select “i” was
active) since the last read.
- The Write Protection has blocked a Write access to a protected register.
and
- Software Reset has been performed while Write Protection was enabled.
and
- Write accesses have been detected on MR (while a chip select was active) or on CSRi
