9.1.1.9.2 Reset Instruction
The Reset instruction resets the internal memory logic state machine in a few milliseconds.
Reset is an instruction of either one write operation or three write operations (refer to
Table 9).

9.1.1.8.4 Flash Erase Resume Instruction
If an Erase Suspend instruction was previously executed, the erase operation may be
resumed by this instruction. The Erase Resume instruction consists of writing 030h to any
address while an appropriate Chip Select (FSi) is true. (See Table 9.)
9.1.1.9 Flash and EEPROM Memory Specific Features
9.1.1.9.1 Flash and EEPROM Sector Protect
Each Flash and EEPROM sector can be separately protected against Program and Erase
functions. Sector Protection provides additional data security because it disables all
program or erase operations. This mode can be activated through the JTAG Port or a
Device Programmer.
Sector protection can be selected for each sector using the PSDsoft Configuration program.
This will automatically protect selected sectors when the device is programmed through
the JTAG Port or a Device Programmer. Flash and EEPROM sectors can be
unprotected to allow updating of their contents using the JTAG Port or a Device
Programmer. The microcontroller can read (but cannot change) the sector protection bits.
Any attempt to program or erase a protected Flash or EEPROM sector will be ignored by
the device. The Verify operation will result in a read of the protected data. This allows a
guarantee of the retention of the Protection status.
The sector protection status can be read by the MCU through the Flash protection and
PSD/EE protection registers (CSIOP). See Table 11.
