Hi, 
 The nRF51x22 series is based on a M0 core, and will support all required functions of a M0 core.
However, there are some (optional) features that are taken out. The SYSTICK is replaced with a more configurable RTC0/1 peripheral for instance. 
 All M0 generic information is found at ARMs site:
 www.arm.com/.../cortex-m0.php 
 Best regards
