Data Wrapping
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
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
