CONFIG_CPU_CORTEX_M_HAS_DWT
¶
(No prompt – not directly user assignable.)
Type: bool
Help¶
This option signifies that the CPU implements the Data Watchpoint and Trace (DWT) unit specified by the ARMv7-M and above.
While ARMv6-M does define a “DWT” unit, this is significantly different from the DWT specified by the ARMv7-M and above in terms of both feature set and register mappings.
Direct dependencies¶
!CPU_CORTEX_M0
&& !CPU_CORTEX_M0PLUS
&& !CPU_CORTEX_M1
&& CPU_CORTEX_M
&& !ARM64
&& ARM
(Includes any dependencies from ifs and menus.)
