The PM0253 is aligned with Arm Cortex-M7 Devices Generic User Guide r1p2 description, but we got confirmation, you can use PRI_12 to set of the priority of debug monitor for Cortex-M7, Cortex-M4, Cortex-M3 and Cortex-M33.

12 being Debug Monitor is also inferred here https://www.keil.com/dd/docs/datashts/arm/cortex_m3/r2p0/ddi0337g_cortex_m3_r2p0_trm.pdf
