Manufacturer:NEC Description:PROGRAM MEMORY The device contains 4096 bytes of UV erasable or OTP EPROM memory This memory is mapped in the program memory address space from 0000 to 0FFF Hex The pro- gram memory may contain either instructions or data con- stants and is addressed by the 15-bit program counter (PC) The program memory can be indirectly read by the LAID (Load Accumulator Indirect) instruction for table lookup of constant data All locations in the EPROM program memory will contain 0FF Hex (all 1s) after the device is erased OTP parts are shipped with all locations already erased to 0FF Hex Un- used EPROM locations should always be programmed to 00 Hex so that the software trap can be used to halt runaway program operation The device can be configured to inhibit external reads of the program memory This is done by programming the security bit in the ECON (EPROM configuration) register to zero See the ECON REGISTER section for more details |
