Abstract:
A USB/UART converter connected between a DTE and a DCE, said USB/UART converter comprising:a USB controller connected to a USB of said DTE, comprising a first register into which control signals and parameters are written: a second register into which status signals are written; a third register into which data supplied from said DCE to said DTE are written; a fourth register into which data supplied from said DTE to said DCE are written; a signal direction controller connected with said registers for regulating said control signals, parameters, status signals and data; anda UART controller connected between said DCE and said USB controller;wherein said control signals for said DCE and said parameters for said UART controller are transferred from said DTE through said USB controller in a control transfer mode; the UART controller transfers status signals through said USB controller to said DTE in an interrupt transfer mode after detecting said status signals from said DCE; and data can be transferred between said DTE and said DCE in an isochronous data transfer mode in response to said parameters.
