最近在调试PSoC63的SPI外设,官方的Demon有High_Level和Low_Level两种,这两者的具体区别是什么?

High_Level和Low_Level是两套不同机制的SPI API,主要区别是High_Level API通过中断的方式执行数据传输,Low_Level API直接操作SCB硬件来完成,具体介绍可以参考PDL文档-> API Reference -> SCB,文档路径通常为 - C:/Program%20Files%20(x86)/Cypress/PDL/3.0.4/doc/pdl_api_reference_manual/html/group__group__scb__spi.html
