The signal indicates there is a minimum of 1 byte of data available to read. Only read from the FIFO when this signal is logic 0. Multi-Channel FIFO mode: Data Receive Acknowledge output signal. O 9 5 SIWU_N Reserved. Add external pull up in normal operation. I 10 6 WR_N 245 Synchronous FIFO mode: Write Enable input signal. Multi-Channel FIFO mode: Data Transaction Request input signal. The signal is active low. I 11 7 RD_N 245 Synchronous FIFO mode: Read Enable input signal. The signal is active low. I 12 8 OE_N 245 Synchronous FIFO mode: Data Output Enable input signal. The signal is active low. I 13 9 RESET_N Chip Reset input, Active low. I 15 10 WAKEUP_N Suspend/Remote Wakeup pin by default Low when USB is active, high when USB is in suspend. Application can drive this pin low in in USB suspend to generate a remote wakeup signal to the USB host. I/O 16 11 Reserved Do not connect. NC 19 14 GPIO0 Configurable GPIO port0. I/O 17 12 GPIO1 Configurable GPIO port1. I/O 18 13 VBUS USB BUS power input. I 37 29 XI Crystal input. This terminal is the crystal input for the internal oscillator. I 21 16 XO Crystal Output. This terminal is the crystal output for the internal oscillator. O 22 17 DP High-speed USB differential transceiver (positive) I/O 23 18 DM High-speed USB differential transceiver (negative) I/O 25 20 RREF PHY reference resistor input pin. Connect 1.6K Ω 1% resistor to ground, provides reference voltage to USB2 PHY. I 27 21 TODN Super Speed USB transmitter differential pair (negative) O 31 24 TODP Super Speed USB transmitter differential pair (positive) O 32 25 RIDN Super Speed USB receiver differential pair (negative) I 34 27 RIDP Super Speed USB receiver differential pair (positive) I 35 28 |
