Device ordering information and transfer of customer code

Customer code is made up of the ROM contents and the list of the selected options (if any).

The ROM contents are to be sent on diskette, or by electronic means, with the hexadecimal

file in .S19 format generated by the development tool. All unused bytes must be set to FFh.

The selected options are communicated to STMicroelectronics using the correctly

completed option list appended (see Section 15.2).

Refer to application note AN1635 for information on the counter listing returned by ST after

code has been transferred.

The STMicroelectronics Sales Organization will be pleased to provide detailed information

on contractual points.

OPT 2 Reserved.

OPT 1 OSC24/12 Oscillator Selection

This option bit selects the clock divider used to drive the USB interface at 6MHz.

0: 24 MHz oscillator

1: 12 Mhz oscillator

OPT 0 FMP_R Flash memory readout protection

This option indicates if the user flash memory is protected against readout.

Readout protection, when selected, provides a protection against program memory

content extraction and against write access to Flash memory. Erasing the option

bytes when the FMP_R option is selected, causes the whole user memory to be

erased first and the device can be reprogrammed. Refer to the ST7 Flash

Programming Reference Manual and Section 4.3.1: Readout protection for more

details.

0: Readout protection enabled

1: Readout protection disabled
