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 && ARM
(Includes any dependencies from ifs and menus.)
Defaults¶
No defaults. Implicitly defaults to n.
