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).
9.1.1.9.3 Programmng and Erasing the Boot Blocks in PSD813F2 and PSD813F4
There are two different algorithms for programming and erasing the Boot Blocks in the
PSD813F2 and F4 (Boot Blocks are selected by CSBOOTi). The selection of the correct
algorithm is based on the internal die of the PSD device, which can be identified based on
the Flash Memory Identifier read by the MCU. Using the Read Flash Identifier instruction
(Table 9), the MCU will read one of two IDs for the PSD813F2 and PSD813F4, as shown in
Table 12.

Table 12. Flash Memory IDValues for PSD813F2 and F4
For users of the PSD813F2 and F4, the MCU system software must make both algorithms
available. Within the routine that programs or erases the Boot Block area, the MCU should
use the Flash Memory Identifier first to select the appropriate algorithm. If the Identifier is
E4h, then it should treat the Boot Block area as Flash memory. If the Identifier is E3h, then
the MCU should treat the Boot Block area as EEPROM. This will ensure compatibility with
all future PSD813F2 and F4 devices.
Note:
The MCU must not operate out of Main Flash while reading the Flash Memory
Identifier. It can execute the Flash Memory Identifier command from some other memory,
and store the ID value for later use.
This algorithm selection method only applies to the PSD813F2 and F4. The PSD813F1 will
always use the EEPROM algorithm for the Boot Block area. The PSD813F3 and F5 have
no Boot Block area.
Note that this algorithm selection method is not required when programming or erasing the
main Flash memory. It only applies to programming or erasing the Boot Block area.
Main Flash will always require the Flash algorithm defined in section 9.1.1.7, regardless of
internal die composition.
