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

礦業(yè)城市是指依托自然礦藏資源優(yōu)勢，并通過開發(fā)利用其資源而發(fā)展起來的 城市。大多傳統(tǒng)礦業(yè)城市都面臨“礦竭城衰”的問題。如何避免“礦竭城衰”達(dá) 到可持續(xù)發(fā)展，是擺在礦業(yè)城市面前的重要問題。礦業(yè)城市發(fā)展中的生態(tài)環(huán)境問 題因其影響范圍廣、潛伏性強(qiáng)、恢復(fù)重建的成本高、周期長、難度大已成為制約 礦業(yè)城市可持續(xù)發(fā)展的“瓶頸”因素。
