tc_oc
• Supports the following modes of operation:
• Programmable clock input source
• Programmable input clock prescaler
• One static interrupt output to routing
• One wake-up interrupt to on-chip standby mode controller.
• Three independent interrupt sources: overflow, output compare match, and input capture
• Auto reload
• Time-stamping support on the input capture unit
• Waveform generation on the output
• Glitch-free PWM waveform generation with variable PWM period
• Internal WISHBONE bus access to the control and status registers
• Stand-alone mode with preloaded control registers and direct reset input
– Watchdog timer
– Clear timer on compare match
– Fast PWM
– Phase and Frequency Correct PWM

Timer/Counter input clock signal
Register tc_rstn_ena is preloaded by configuration to always keep this pin enabled
Input capture trigger event, applicable for non-pwm modes with WISHBONE interface. If
enabled, a rising edge of this signal will be detected and synchronized to capture tc_cnt value
into tc_icr for time-stamping.
Without WISHBONE – Can be used as overflow flag
With WISHBONE – Controlled by three IRQ registers
