4.2.7.2. UFM Data Wrapping Burst Read

The UFM supports data wrapping when it receives an unaligned address.
Note: Wrapping burst read is available only for parallel interface.
Table 6.  Data Wrapping Support for Intel® MAX® 10 Devices
Device Data Register Length Flash IP Data Bus Width Fixed Supported Burst Count Data Wrapping
10M02SCU324, 10M04, or 10M08 32 64 2 The address wraps back to the previous boundary after 64 bits or 2 cycles. For example, for a wrapping in a 32-bit data interface:
  1. Start address is 0×01
  2. Address sequence will be 0×01, then back to address 0×00
10M16, 10M25, 10M40, or 10M50 32 128 4 The address wraps back to the previous boundary after 128 bits or 4 cycles. For example, for a wrapping in a 32-bit data interface:
  1. Start address is 0×02
  2. Address sequence will be 0×02 and 0×03, then back to address 0×00 and 0×01

The following figures show the timing diagrams for the data wrapping burst read operations for the different Intel® MAX® 10 devices.
