NXP Semiconductors K22F series - Modes of Operation

• Each channel can be configured for input capture, output compare, or edge-aligned
PWM mode
• In Input Capture mode:
• The capture can occur on rising edges, falling edges or both edges
• An input filter can be selected for some channels
• In Output Compare mode the output signal can be set, cleared, or toggled on match
• All channels can be configured for center-aligned PWM mode
• Each pair of channels can be combined to generate a PWM signal with independent
control of both edges of PWM signal
• The FTM channels can operate as pairs with equal outputs, pairs with
complementary outputs, or independent channels with independent outputs
• The deadtime insertion is available for each complementary pair
• Generation of match triggers
• Initialization trigger
• Software control of PWM outputs
• Up to 4 fault inputs for global fault control
• The polarity of each channel is configurable
• The generation of an interrupt per channel
• The generation of an interrupt when the counter overflows
• The generation of an interrupt when the fault condition is detected
• Synchronized loading of write buffered FTM registers
• Write protection for critical registers
• Backwards compatible with TPM
• Testing of input captures for a stuck at zero and one conditions
• Dual edge capture for pulse and period width measurement
• Quadrature decoder with input filters, relative position counting, and interrupt on
position count or capture of position count on external event
