They offer the same functionality as OTP devices, selecting as ROM options the options defined in the programmable option byte of the OTP version, with the exception of the LVD Reset that is not available. Figure 1. Programming wave form 1.2 ROM READOUT PROTECTION If the ROM READOUT PROTECTION option is selected, a protection fuse can be blown to prevent any access to the program memory content. In case the user wants to blow this fuse, high voltage must be applied on the TEST pin. Figure 2.

Date ............................. 3/10 1 ST6215L/25L 1.3 ORDERING INFORMATION The following section deals with the procedure for transfer of customer codes to SGS-THOMSON. 1.3.1 Transfer of Customer Code Customer code is made up of the ROM contents and the list of the selected mask options. The ROM contents are to be sent on diskette, or by electronic means, with the hexadecimal file generated by the development tool. All unused bytes must be set to FFh. The selected mask options are communicated to SGS-THOMSON using the correctly filled OPTION LIST appended. 1.3.2 Listing Generation and Verification When SGS-THOMSON receives the user’s ROM contents, a computer listing is generated from it. This listing refers exactly to the mask which will be used to produce the specified MCU. The listing is then returned to the customer who must thoroughly check, complete, sign and return it to SGS-THOMSON. The signed listing forms a part of the contractual agreement for the creation of the specific customer mask. Table 3.
