The MAX V UFM block is organized as a 512 × 16 memory. Because the UFM block is
organized into two sectors, the MSB of the address indicates the sector that is used; 0
is for sector 0 (UFM0) while 1 is for sector 1 (UFM1). An ERASE instruction erases the
content of the specific sector that is indicated by the MSB of the address register.

For more information about the erase mode, refer to
Three control signals exist for the address register: ARSHFT, ARCLK, and ARDin. ARSHFT is
used as both a shift-enable control signal and an auto-increment signal. If the ARSHFT
signal is high, a rising edge on ARCLK loads address data serially from the ARDin port
and moves data serially through the register. A clock edge with the ARSHFT signal low
increments the address register by 1. This implements an auto-increment of the
address to allow data streaming. When a program, read, or erase sequence is
executing, the address that is in the address register becomes the active UFM location.
