This manual is intended as a technical resource for part numbers Z8030, Z80C30 and Z80230 (Z-Bus) as well as The document is organized into nine chapters as follows: Z8530, Z85C30, Z85230, and Z85233 (Universal Bus). If 1. General Description Chapter 1 is an introductory section covering the key features and giving an overview of block diagrams, pin-outs, pin definitions and signal functions. 2. Interfacing the SCC/ESCC Chapter 2 provides all of the technical information to describe the bus inter faces. Included are timing diagrams, register accesses, resets, interrupts, Read/Write cycles, programming, OMAs and test functions. 3. SCC/ESCC Ancillary Support Circuitry Chapter 3 covers the SCC's/ESCC's functional details in the areas of baud rate generator, data encoding/decoding, digital phased-lock loop (NRZI, FM, Manchester modes), transmit clock counter, clock selection and crystal oscillator. 4. Data Communication Modes Chapter 4 explains the transmit/receive data paths, asynchronous modes, byte- oriented synchronous modes, and bit-oriented synchronous (SOLC/HOLC) modes. 5. Register Descriptions Chapter 5 illustrates and explains all of the bit and byte functions of the Read/Write registers. 6. Z85C30 SL 1480 Enhancements Chapter 6 explains the SOLC enhancements. Application Notes This section provides examples and useful tips to aid in development of SCC/ESCC Applications.
