NXP Semiconductors K22F series User Manual

39.6.1 Timer Overflow Interrupt
The timer overflow interrupt is generated when (TOIE = 1) and (TOF = 1).
39.6.2 Channel (n) Interrupt
The channel (n) interrupt is generated when (CHnIE = 1) and (CHnF = 1).
39.6.3
Fault Interrupt
The fault interrupt is generated when (FAULTIE = 1) and (FAULTF = 1).
39.7
Initialization Procedure
The following initialization procedure is recommended to configure the FlexTimer
operation. This procedure can also be used to do a new configuration of the FlexTimer
operation.
• Define the POL bits.
• Mask the channels outputs using SYNCHOM = 0. Two clocks after the write to
OUTMASK, the channels output are in the safe value.
• (Re)Configuration FTM counter and channels to generation of periodic signals -
Disable the clock. If the selected mode is Quadrature Decoder, then disable this
mode. Examples of the (re)configuration:
• Write to MOD.
• Write to CNTIN.
• Select OC, EPWM, CPWM, Combine, Complement modes for all channels that
will be used
• Select the high-true and low-true channels modes.
• Write to CnV for all channels that will be used .
• (Re)Configure deadtime and fault control.
• Do not use the SWOC without SW synchronization (see item 6).
• Do not use the Inverting without SW synchronization (see item 6).
• Do not use the Initialization.
• Do not change the polarity control.
• Do not configure the HW synchronization
