2.6 I/O BANK Introduction
There are four I/O Banks in the GW1NRF series of FPGA products.
The I/O BANK Distribution of the GW1NRF series of Bluetooth FPGA
products is as shown in Figure 2-1.

This manual provides an overview of the distribution view of the
pins in the GW1NRF series of Bluetooth FPGA products. The four I/O
Banks that form the GW1NRF series of Bluetooth FPGA products are
marked with four different colors.
Various symbols are used for the user I/O, power, and ground. The
various symbols and colors used for the various pins are defined as
follows:

" " denotes the I/O in BANK0. The filling color changes with the
BANK;

" " denotes the I/O in BANK1. The filling color changes with the
BANK;

" " denotes the I/O in BANK2. The filling color changes with the
BANK;

" " denotes the I/O in BANK3. The filling color changes with the
BANK;

" " denotes VCC, VCCX, and VCCO. The filling color does not
change;

" " denotes VSS, the filling color does not change;

" " denotes NC;

“ ” denotes BLE, the filling color does not change.
