Breakpoints
Overview
dard. This includes enabling the AUX port, and controlling the speed of the clock and data
compared to the CPU clock.
Table 9-22.
The Nexus Recommended Register map supports up to 8 universal breakpoints. However since
the AVR32UC hardware employs separate instruction and data memories, the OCD system
must also separate program and data breakpoints. Any breakpoint can also be programmed as

Description
Reserved
These bits are reserved, and will always read as 0
AXS - Auxiliary Port Select
0: AUX port is mapped to pin configuration 0.
1: AUX port is mapped to pin configuration 1.
2: AUX port is mapped to pin configuration 2.
3: AUX port is mapped to pin configuration 3.
Reserved
This bit is reserved, and will always read as 0
Reserved
This bit is reserved, and will always read as 0.
LS - Low Speed
0:AUX port runs at the same speed as the CPU
1:AUX port runs at reduced speed compared to
the CPU.
DDR - Double Data Rate
Setting this bit halves the MCKO rate so that MDO
data must be sampled on both edges of MCKO.
1 = Double data rate mode
0 = Single datarate mode
AXO - Auxiliary Port Override
0: AUX port is mapped to the pins dictated by
AXS.
1: AUX port is overridden and mapped to pin
configuration 1.
AXE - Auxiliary Port Enable
0: AUX port is used for GPIO
1: AUX port is used for Nexus operation.
This bit does not need to be written in devices with
dedicated AUX pins
Reserved
These bits are reserved, and will always read as 0
DIV - Division factor
If LS=1, the DIV value selects the frame rate of the
AUX port.
