在過去各種電子裝置的溝通或連接都需要依照相對應的傳輸線,且在充電或供電上,也需要相對應的線材,所以隨著時間的累積,科技的進步,線材以及供電配件會不斷地更新以及淘汰,造成資源的浪費以及環保的問題,而USB-IF協會推出了一個將資料傳輸以及電力傳輸合為一體的規範,就是USB Type-C規格以及USB Power Delivery規範。為了符合這兩項技術的規格,相對應的硬體規格也產生出來了,此類產品又分為兩類USB-PD Controllers和TCPC。In the past, the communication or connection of various electronic devices required corresponding transmission lines, and corresponding wires were required for charging or power supply. Therefore, with the accumulation of time and technological advancement, the wires and power supply accessories will be constantly updated And elimination, resulting in waste of resources and environmental issues, and the USB-IF Association has launched a specification that integrates data transmission and power transmission, which is the USB Type-C specification and the USB Power Delivery specification. In order to comply with the specifications of these two technologies, corresponding hardware specifications have also been produced. Such products are divided into two types of USB-PD Controllers and TCPC.
以TCPC(Type-C Port Controller)基礎實現含有USB Type-C及USB PD規格的系統上,會含有TCPM(Type-C Port Manager)和TCPC(Type-C Port Controller)兩個區塊,以及TCPCI(Type-C Port Controller Interface)介面。TCPM在系統上屬於Master,PD中屬於應用層,用來判斷PD的資訊及處理所接收到的資訊;TCPC在系統上屬於Slave,PD中屬於實體層,用來傳接PD資料的物理訊號,但除了PD資料的處理,還會控制或判斷Type-C實體端口上的訊號。而TCPCI是使用I2C protocol,來當作兩者之間的橋樑,I2C protocol具有可掛載多個Device的優點。Based on TCPC (Type-C Port Controller) to realize the system with USB Type-C and USB PD specifications, there will be two blocks, TCPM (Type-C Port Manager) and TCPC (Type-C Port Controller), and TCPCI (Type-C Port Controller Interface) interface. TCPM belongs to the Master in the system, and the PD belongs to the application layer, which is used to determine the information of the PD and process the received information; TCPC belongs to the Slave in the system, and the PD belongs to the physical layer, which is used to transmit the physical signal of PD data. But in addition to PD data processing, it also controls or judges the signal on the Type-C physical port. TCPCI uses the I2C protocol as a bridge between the two. The I2C protocol has the advantage of being able to mount multiple devices.
TCPC的硬體規格上會有許多暫存器,有分為狀態、控制、封包傳遞、VBUS電壓等暫存器類別,例如:POWER_STATUS、POWER_CONTROL、TRAMSMIT_BUFFER、RECEIVE_BUFFER、VBUS_VOLTAGE…等,暫存器是透過I2C Protocol做讀取寫入的動作。在TCPC系統應用上,TCPM與TCPC透過I2C做溝通,每次資料的溝通都是一方傳送8位元的資料後,另一方會回傳一個ACK代表傳輸成功,若回傳NACK代表失敗。There are many registers in the hardware specifications of TCPC, which are divided into categories such as status, control, packet transfer, VBUS voltage, etc., such as: POWER_STATUS, POWER_CONTROL, TRANSMIT_BUFFER, RECEIVE_BUFFER, VBUS_VOLTAGE... etc. The register is through I2C Protocol does read and write operations. In the TCPC system application, TCPM and TCPC communicate through I2C. Each time one party transmits 8-bit data, the other party will return an ACK to indicate a successful transmission. If a NACK is returned, it indicates a failure.
VBUS_VOLTAGE的數值代表著Type-C的VBUS電壓大小,這個類比電壓會透過ADC電路轉成數位數值10位元的數值。但因為TCPC硬體的暫存器寬度為8位元,所以整筆資料會分別存放於兩個暫存器,在此將它們分別命名為VBUS_VOL_HBYTE_REG及VBUS_VOL_LBYTE_REG,前面2個位元存放於VBUS_VOL_HBYTE_REG,後面8個位元存放於VBUS_VOL_LBYTE_REG,且隨著VBUS電壓的變化,會更新這兩個暫存器的值。所以當TCPM要讀取VBUS_VOLTAGE資料時,會先讀取VBUS_VOL_LBYTE_REG,後讀取VBUS_VOL_HBYTE_REG,當讀取前面一個暫存器時,後面的暫存器有機會因為VBUS電壓的變化而改變,使得讀取到的數值與理想的數值不同步,使得讀取的資料會有極大的誤差,造成系統的錯誤。The value of VBUS_VOLTAGE represents the VBUS voltage of Type-C. This analog voltage will be converted into a digital value of 10 bits through the ADC circuit. However, because the register width of the TCPC hardware is 8 bits, the entire data will be stored in two registers respectively. Here, they are named VBUS_VOL_HBYTE_REG and VBUS_VOL_LBYTE_REG. The first two bits are stored in VBUS_VOL_HBYTE_REG, and the
