• Write any value to CNT. The FTM Counter is reset and the channels output are
updated according to new configuration.
• Enable the clock. Write to CLKS[1:0] bits a value different from zero. If in the
Quadrature Decoder mode, enable this mode.
• Configure the SW synchronization for SWOC (if it is necessary), Inverting (if it is
necessary) and Output Mask (always)
• Select synchronization for Output Mask Write to SYNC (SWSYNC = 0, TRIG2
= 0, TRIG1 = 0, TRIG0 = 0, SYNCHOM = 1, REINIT = 0, CNTMAX = 0,
CNTMIN = 0)
• Write to SYNCONF.
• HW Synchronization can not be enabled (HWSOC = 0, HWINVC = 0,
HWOM = 0, HWWRBUF = 0, HWRSTCNT = 0, HWTRIGMODE = 0).
• SW Synchronization for SWOC (if it is necessary): SWSOC = [0/1] and
SWOC = [0/1].
• SW Synchronization for Inverting (if it is necessary): SWINVC = [0/1] and
INVC = [0/1].
• SW Synchronization for SWOM (always): SWOM = 1. No enable the SW
Synchronization for write buffers (because the writes to registers with write
buffer are done using CLKS[1:0] = 2’b00): SWWRBUF = 0 and CNTINC =
0 .
• SW Synchronization for counter reset (always): SWRSTCNT = 1.
• Enhanced synchronization (always): SYNCMODE = 1
• If the SWOC is used (SWSOC = 1 and SWOC = 1), then write to SWOCTRL
register.
• If the Inverting is used (SWINVC = 1 and INVC = 1), then write to INVCTRL
register.
• Write to OUTMASK to enable the masked channels.
• Generate the Software Trigger Write to SYNC (SWSYNC = 1, TRIG2 = 0, TRIG1 =
0, TRIG0 = 0, SYNCHOM = 1, REINIT = 0, CNTMAX = 0, CNTMIN = 0)
