This bit is used to select the source of events which trigger the capture of the
[MTIM:MTIML] counter when using Encoder speed sensor (see
0: Real Time Clock interrupts
1: Read access on MTIM register
This setting is effective only if PCN = 0, TES = 00 and SR = 0.
0: Unused MCIx inputs are grounded
1: Unused MCIx inputs are put in HiZ
