4.6 Pipe Definition

4.6.1 Overview

When using the device in peripheral mode, the PDCD (the class driver) must store appropriate pipe settings as a pipe

information table.

A sample pipe information table for the peripheral sample program is in file r_usb_vendor_descriptor.c.

4.6.2 Pipe information table

A pipe information table comprises the following six items (uint16_t × 6).

1. Pipe Window Select register (address 0x64)

2. Pipe Configuration register (address 0x68)

3. Pipe Buffer Designation register (address 0x6A)

4. Pipe Maximum Packet Size register (address 0x6C)

5. Pipe Period Control register (address 0x6E)

6. FIFO port usage method

4.6.3 Definition of pipes 1 to 9

The pipe definitions provided as a sample in USB-BASIC-FW are configured as shown below.

Possible pipe values that can be set in the pipe information table are defined as macros in the r_usb_cdefusbip.h file.
