The JTAGSEL_N pin and four JTAG pins (TCK, TMS, TDI, and TDO) configured as GPIO
are exclusive. JTAG pins can only be used as configuration pin if JTAGSEL_N is set to
GPIO. JTAGSEL_N can only be used as a configuration pin if JTAG pins are set to GPIOs.

FASTRD_N

Overview

MSPI configuration mode reads the SPI Flash speed selection signal.

When FASTRD_N is high, it is normal read mode. When FASTRD_N is low,
it is high speed read mode. Different manufacturers have different
high-speed read operation instructions, please refer to the corresponding
Flash datasheet.

Description

FASTRD_N

I/O



As a configuration pin, internal weak pull-up,
READY signal rising edge samples MSPI
configuration speed mode;



As a GPIO, it can be used as input or output.

Note!



High level: Normal Flash mode, clock frequency should not be higher than 30MHz;



Low level: High speed Flash mode, clock frequency should be > 30MHz and <
80MHz

Configure Dual-purpose Pin

Overview

Dual-purpose pin configuration refers to performing configuration

function at the moment of power-on. After downloading bitstream files, it is
used as general I/O.

The steps are as follows:

1. Open the project in Gowin software;

2. Select "Project > Configuration > Dual Purpose Pin" from the menu, as

shown in Figure 5;

3. Check the corresponding options.
