Abstract: A system-on-chip integrated circuit includes a peripheral initialization register has a bit corresponding to each module. Each bit indicates a normal mode or a reset mode for the corresponding module. A direct memory access unit can receive, prioritize and queue date movement transactions between modules and can read from or write to the peripheral initialization register. A peripheral interface unit prevents a write to the peripheral initialization register changing a module from reset mode to normal mode while there is an uncompleted data movement transaction involving that module. A false acknowledge circuit for each module supplies an acknowledge signal in response to a received command if the module is in reset mode.

Abstract translation: 片上系统集成电路包括外设初始化寄存器，其中每个模块都有一个位。 每个位表示相应模块的正常模式或复位模式。 直接存储器访问单元可以接收，优先排列和排队模块之间的日期移动事务，并且可以从外设初始化寄存器读取或写入外部初始化寄存器。 外围接口单元防止写周围初始化寄存器将模块从复位模式更改为正常模式，同时存在涉及该模块的未完成数据移动事务。 如果模块处于复位模式，每个模块的错误确认电路将响应于接收到的命令提供一个确认信号。
