Hi all,
I am using ATSAMC21G18A-MUT.
I previously used ATXMEGA which had different datasheet and manual.
Somehow SAM21C seems difficult to start with. Are there any basic examples (non-ASF coding) to configure basic clock and start using PORTS pins? 
And is there only one datasheet for SAMC21 series? No separate manual for registers like for XMEGA?

For example, if i want to enable OSC48M, how do I access it? Which file I have to look into to get the names for accessing. The names mentioned in datasheet e.g OSC48MCRTL can't be accessed directly
Also what is a non-ASF way of accessing and writing to 32 bit registers?

Alex Taradov (AVRFreak alexru) has some starter projects on GitHub.

For manuals there are the ARM Cortex M0+ TRM and User's Guide.

And the Datasheet covers each of the peripherals...
