The document is a Chinese-language programming guide from Guangzhou Zhouli Microcontroller Development Co., Ltd. (ZLG) for the ISP1581 high-speed USB 2.0 interface device. It explains how to implement ISP1581 hardware and firmware on a general-purpose processor interface with a 16-bit data bus.
It lists microcontroller interface signal connections and DMA connections, describes power-on reset configuration, and gives initialization tables for the mode, interrupt, DMA configuration, and DMA hardware registers. It also outlines the ISP1581 firmware structure, file roles, and USB command handling flow. This manual is written in Chinese.
| USB interface | High-speed USB 2.0 interface device |
|---|---|
| Generic processor interface | 16-bit data bus and 8-bit address lines |
| BUS_CONF setting | 1 = generic microprocessor interface |
| Mode register address | 0CH |
| Interrupt configuration register address | 10H |
| DMA configuration register address | 38H |
It is a high-speed USB 2.0 interface device.
It uses a 16-bit data bus and 8-bit address lines.
It scans USB events in a loop and starts device and system operation.
