The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4- bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the W78E58B allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security

QuickSteps books are recipe books for computer users. They answer the question 揌ow do I...??by providing a quick set of steps to accomplish the most common tasks with a particular program. The sets of steps are the central focus of the book. Sidebar QuickSteps provide information on how to do quickly many small functions or tasks that are in support of the primary functions. Sidebar QuickFacts supply information that you need to know about a subject. Notes, Tips, and Cautions augment the steps, but they are presented in a separate column to not interrupt the fl ow. Brief introductions are present, but there is minimal narrative otherwise. Many illustrations and fi gures, a number with callouts, are also included where they support the steps.
