Adjust the Programming Pulse Width of FLASH MCUs and choose Target Power Options for ICP
(In-Circuit Programming).
FLASH Programming Pulse Width:
Alt+O, N
Modify this setting in "Less than Optimal" situations to ensure successful programming over
voltage, temperature, device and circuit variations.
Place in Code Memory - If selected, the Serial number will be programmed into the Code area
of the MCU. This also enables access to the Encode as RETLW option.
Encode as RETLW - This option is only available if the CODE memory option is selected. If
selected, each Serial number location will be converted into the proper RETLW OPCODE
(return literal in W) for the currently selected MCU.
Place in EEPROM Memory - If selected, the Serial number will be programmed into the EE
DATA area of the MCU. This also Disables access to the Encode as RETLW option.
Number of Locations - Enter the maximum number of locations the serial number will need
(from 1 to 8). Each byte of the serial number will use 1 location in the memory area specified.
Place at Address - Enter the address in the selected memory area to place the serial number.
This can be from 0 to the highest available address, minus the number of locations specified. If
an address higher than the maximum valid address is specified, QuickWriter will notify you and
automatically reduce the address to the highest valid address for the selected memory area and
number of locations.

The default value of Tmin is preset to the Factory Recommended Value that already accounts
for temperature and device variations. However if errors occur when programming In-circuit, this
value may need to be adjusted to account for Voltage and Circuit variations.
Each step in the selector (shown above) will increase the duration of the programming pulse by
1/4 of the Factory Recommended Value. The 5 steps are as follows:
PPW = Tmin or 1 PPW
PPW = (Tmin + (Tmin /4)) or 1.25 PPW
PPW = (Tmin + ((Tmin /4) * 2)) or 1.50 PPW
PPW = (Tmin + ((Tmin /4) * 3)) or 1.75 PPW
PPW = (Tmin * 2) or 2 PPW
