PL2303GL OTPROM的用户区域现在可以通过USB端口使用Prolific OTPROM软件轻松编程，无需任何额外的电压转换器要求。有关OTPROM配置设置的更多信息，请参阅第9.0节。8.15多路复用器/多路复用器此模块设计用于在FIFO和UART外围模块之间传递数据。8.16描述符ROM此块包含用于返回USB主机的USB描述符数据。8.17 UART控制UART控制模块根据RS232格式和接口处理数据传输。全套流量控制包括RTS/CTS、DTR/DSR和软件流量控制。流量控制电路将检查FIFO接近满或接近空状态，以激活流量控制信号。该模块还包括一个精确的波特率发生器。8.18控制寄存器控制寄存器模块包含读取和设置的芯片控制寄存器，并最初从OTPROM加载。USB主机将使用USB供应商命令读取和写入控制寄存器，以设置芯片功能。产品数据表PL2303GL发布日期：2018年12月6日-16/23-Rev.0.8 9。芯片功能配置默认配置描述符存储在芯片内部存储器中，当OTPROM（一次性可编程ROM）为空时，将在通电复位或USB总线复位期间加载。使用PL2303GL OTPROM Writer实用程序，可以修改几个USB和配置描述符，并将其一次性编程到芯片的OTPROM中。这些描述符包括供应商ID、产品ID、序列号、产品字符串和其他USB配置描述符。图9-1 PL2303GL OTPROM写入工具产品数据表PL2303GR版本：2018年12月6日-17/23-版本0.8表9-1 USB描述符配置描述符默认值描述OTPROM空间1此字段表示可写入OTPROM的剩余空间（1或0）。OTPROM只能写入一次，不能擦除。如果值为0，则表示OTPROM已写入一次。公司或制造商的供应商ID（VID）067B（十六进制）USB唯一供应商ID。该ID从USB-IF应用和注册。有关申请VID的信息，请参阅本网站：http://www.usb.org/developers/vendor/公司或制造商分配的产品ID（PID）23D3（十六进制）USB产品ID。版本号（BCD）0100（十六进制）此字段报告USB设备的版本号。无法修改此项目。
The user area of the PL2303GL OTPROM can now be easily programmed using the Prolific OTPROM software through USB port without any additional voltage converter requirement. Refer to Section 9.0 for more information on the OTPROM configuration settings. 8.15 Mux/Demux This module is designed to pass data between FIFO and UART peripheral module. 8.16 Descriptor ROM This block contains the USB descriptor data for returning to USB host. 8.17 UART Control The UART Control module handles the data transfer according to RS232 format and interface. Full set flow control is implemented including RTS/CTS, DTR/DSR and software flow control. Flow control circuit will check FIFO near full or near empty status to activate flow control signals. This module also includes a precise baud rate generator. 8.18 Control Registers The Control Registers module contains the chip control registers read and set, and initially loads from OTPROM. USB host will use USB vendor command to read and write control registers to set chip function. Product Data Sheet PL2303GL Release: Dec. 6, 18 - 16 / 23 - Rev.0.8 9. Chip Function Configuration The default configuration descriptors are stored in the chip internal memory which will be loaded during power-on reset or USB bus reset whenever OTPROM (One-Time Programmable ROM) is empty. Several of the USB and configuration descriptors could be modified and programmed one-time into the chip’s OTPROM using the PL2303GL OTPROM Writer utility program. These descriptors include Vendor ID, Product ID, Serial Number, Product String, and other USB configuration descriptors. Figure 9-1 PL2303GL OTPROM Writer Tool Product Data Sheet PL2303GL Release: Dec. 6, 18 - 17 / 23 - Rev.0.8 Table 9-1 USB Descriptor Configuration Descriptors Default Value Description OTPROM Space 1 This field indicates the space left for the OTPROM that can be written (1 or 0). The OTPROM can only be written once and cannot be erased. If value is 0, it means OTPROM has already been written once. Vendor ID (VID) 067B (hex) USB unique Vendor ID of Company or Manufacturer. This ID is applied and registered from USB-IF. Refer to this website for applying VID: http://www.usb.org/developers/vendor/ Product ID (PID) 23D3 (hex) USB Product ID assigned by Company or Manufacturer. Release No. (BCD) 0100 (hex) This field reports the release number of the USB device. This item cannot be modified.
