tc_config Struct Reference

TC configuration structure.

Configuration struct for a TC instance. This structure should be initialized by the tc_get_config_defaults function before being modified by the user application.

enum tc_clock_prescaler tc_config::clock_prescaler

Specifies the prescaler value for GCLK_TC.

Referenced by tc_get_config_defaults(), and tc_init().

enum gclk_generator tc_config::clock_source

GCLK generator used to clock the peripheral.

Referenced by tc_get_config_defaults(), and tc_init().

enum tc_count_direction tc_config::count_direction

Specifies the direction for the TC to count.

Referenced by tc_get_config_defaults(), and tc_init().

struct tc_16bit_config tc_config::counter_16_bit

Struct for 16-bit specific timer configuration.

Referenced by configure_tc(), tc_get_config_defaults(), and tc_init().

struct tc_32bit_config tc_config::counter_32_bit

Struct for 32-bit specific timer configuration.

Referenced by tc_init().

struct tc_8bit_config tc_config::counter_8_bit

Struct for 8-bit specific timer configuration.

Referenced by tc_init().

enum tc_counter_size tc_config::counter_size

Specifies either 8-, 16-, or 32-bit counter size.

Referenced by configure_tc(), tc_get_config_defaults(), and tc_init().

bool tc_config::double_buffering_enabled

Set to true to enable double buffering write.

When enabled any write through tc_set_top_value(), tc_set_compare_value() and will direct to the buffer register as buffered value, and the buffered value will be committed to effective register on UPDATE condition, if update is not locked.

Referenced by tc_get_config_defaults(), and tc_init().

bool tc_config::enable_capture_on_channel[NUMBER_OF_COMPARE_CAPTURE_CHANNELS]

Specifies which channel(s) to enable channel capture operation on.

Referenced by tc_get_config_defaults(), and tc_init().

bool tc_config::enable_capture_on_IO[NUMBER_OF_COMPARE_CAPTURE_CHANNELS]

Specifies which channel(s) to enable I/O capture operation on.

Referenced by tc_get_config_defaults(), and tc_init().

bool tc_config::on_demand

Run on demand.

Referenced by tc_get_config_defaults(), and tc_init().

bool tc_config::oneshot

When true, one-shot will stop the TC on next hardware or software re-trigger event or overflow/underflow.

Referenced by tc_get_config_defaults(), and tc_init().

struct tc_pwm_channel tc_config::pwm_channel[NUMBER_OF_COMPARE_CAPTURE_CHANNELS]

Specifies the PWM channel for TC.

Referenced by tc_get_config_defaults(), and tc_init().

enum tc_reload_action tc_config::reload_action

Specifies the reload or reset time of the counter and prescaler resynchronization on a re-trigger event for the TC.

Referenced by tc_get_config_defaults(), and tc_init().

bool tc_config::run_in_standby

When true the module is enabled during standby.

Referenced by tc_get_config_defaults(), and tc_init().

enum tc_wave_generation tc_config::wave_generation

Specifies which waveform generation mode to use.

Referenced by tc_get_config_defaults(), and tc_init().

uint8_t tc_config::waveform_invert_output

Specifies which channel(s) to invert the waveform on.

For SAM L21/L22/C20/C21, it's also used to invert I/O input pin.
