GENERAL DESCRIPTION
The MS51 Flash supports In-Application-Programming (IAP) function, which enables onchip firmware updates. IAP also makes it possible to configure any block of User Code array to be used as non-volatile data storage, which is written by IAP and read by IAP or MOVC instruction, this function means whole 8K Bytes area all can be use as Data Flash through IAP command. MS51 support an function of configurationable Flash from APROM called LDROM, in which the Boot Code normally resides for carrying out In-System-Programming (ISP). The LDROM size is configurable with a maximum of 4K Bytes by CONFIG define. There is an additional include special 128 bytes security protection memory (SPROM) to enhance the security and protection of customer application. To facilitate programming and verification, the Flash allows to be programmed and read electronically by parallel Writer or In-Circuit-Programming (ICP). Once the code is confirmed, user can lock the code for security. The MS5...
