1.4.12. 4-byte Addressing Exit Operation for an EPCQ256/EPCQ-L256 or Larger Devices

The ex4b_addr input port allow you to exit the 4-byte addressing operation. These input ports are available when you use an EPCQ256/EPCQ-L256 or larger devices.
Note: The 4-byte addressing exit operation is supported for EPCQ256/EPCQ-L256 or larger devices only, so you must enable 4-byte addressing when you use an EPCQ256/EPCQ-L256 or larger devices.

To exit 4-byte addressing mode, pull the wren signal high, followed by at least one clock cycle. If wren signal is zero, the 4-byte addressing mode exit operation will not be carried out even though the ex4b_addr is high. After the IP core receives the command, the IP core asserts the busy signal to indicate that the exit operation is in progress.
