7 / 70 page 7/70 ST62T08C/T09C ST62T10C/T20C/E20C MEMORY MAP (Cont’d) 1.3.2 Program Space Program Space comprises the instructions to be executed, the data required for immediate ad- dressing mode instructions, the reserved factory test area and the user vectors. Program Space is addressed via the 12-bit Program Counter register (PC register)Program Memory Protection. The Program Memory in OTP or EPROM devices can be protected against external readout of mem- ory by selecting the READOUT PROTECTION op- tion in the option byte. In the EPROM parts, READOUT PROTECTION option can be disactivated only by U.V. erasure that also results into the whole EPROM context erasure. Note: Once the Readout Protection is activated, it is no longer possible, even for STMicroelectronics, to gain access to the OTP contents. Returned parts with a protection set can therefore not be ac- cepted. Figure 4.
