In such cases, entering an amount of milliseconds in the Additional Power On Time box results in an

power is turned on before flash programming begins. For the EV0338, an
additional power-on time of 200 ms is recommended to allow the power-on reset to settle.
8.4.2 Additional Write Time Per Word
For some flash MCUs, you can adjust the write time per word specified in the .PRC file upward by
providing an additional time. If this is possible, the FP4MST program prompts you to specify the
additional amount of time. The default amount can be set in this section of OPTMST. Most devices do
not require this parameter, but for those that do, a nominal value of 50 microseconds (µs) is
suggested. Select the Automatic check box if you want to avoid having to answer the prompt for this
value each time the .PRC file is selected.
8.4.3 Pre-Write Time Per Word
For some flash MCUs, you can adjust the pre-write time (used in erasing) specified in the .PRC file
upward. If this is possible, the FP4MST program prompts you to specify the additional amount of time.
The default amount can be set in this section of OPTMST. Most devices do not require this parameter,
but for those that do, a nominal value of 50 µs is suggested. Select the Automatic check box if you
want to avoid having to answer the prompt for this value each time the .PRC file is selected.
8.5 File Selections
This box shows the current setting in the .PRC file for programming, based on the last-selected .PRC
file when FP4MST was run. Selecting the Automatically load on startup check box results in this
.PRC file being automatically loaded and the .PRC file selection step being bypassed.
