Each MTIM includes four registers:
Refer to the direct-page register summary in the
assignments for all MTIM registers.This section refers to registers and control bits only by their names and
relative address offsets.
Some MCUs may have more than one MTIM, so register names include placeholder characters to identify
which MTIM is being referenced.
