CONFIG_PERCEPIO_RECORDER_CFG_MAX_ISR_NESTING

Max ISR Nesting

Type: int

Help

Defines how many levels of interrupt nesting the recorder can handle, in
case multiple ISRs are traced and ISR nesting is possible. If this
is exceeded, the particular ISR will not be traced and the recorder then
logs an error message. This setting is used to allocate an internal stack
for keeping track of the previous execution context (4 byte per entry).
