Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = ZSV Z Event Sampling Validation when
MOE bit is reset
This bit enables/disables Z event sampling in ei-
ther mode (sampling at PWM frequency or at f
frequency selected by SCF[1:0] bits)
0: Z event sampling disabled
1: Z event sampling enabled
Bits 6:4 = Reserved, must be kept cleared.
Bits 3:2 = SCF[1:0] Sampling Clock Frequency
These bits select the sampling clock frequency

Bit 1 = ECM: Encoder Capture Mode
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
