Efficient Bit-Banged SPI Port for 8051-Compatible Microcontrollers

资料介绍
A fast SPI port can be bit-banged through GPIO pins and serve as a lower cost alternative to 8051-compatible microcontrollers with SPI ports. The code shown in this application note takes advantage of 8051-specific features to create a fast SPI port using minimal extra code. ……
