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 SPI_MR, SPI_IER, SPI_IDR or SPI_CSRx).
Both Write Protection violation and software reset with Write Protection enabled have occurred
since the last read.
Write accesses have been detected on SPI_MR (while a chip select was active) or on SPI_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 SPI_MR (while a chip select was active) or on SPI_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 SPI_MR, SPI_IER, SPI_IDR or SPI_CSRx) and some write
accesses have been detected on SPI_MR (while a chip select was active) or on SPI_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 SPI_MR (while a chip select was active) or on SPI_CSRi
(while the Chip Select “i” was active) since the last read.
