Capture input edge select.

sl_hal_sysrtc_compare_match_out_action_t#

sl_hal_sysrtc_compare_match_out_action_t

Compare match output action mode.

value#

uint8_t uint32_t value

sl_hal_sysrtc_init#

void sl_hal_sysrtc_init (const sl_hal_sysrtc_config_t * p_config)

Initializes SYSRTC module.

Note that the compare values must be set separately with (sl_hal_sysrtc_set_group_compare_channel_value()), which should probably be done prior to the use of this function if configuring the SYSRTC to start when initialization is completed.

sl_hal_sysrtc_enable#

void sl_hal_sysrtc_enable (void )

Enables SYSRTC counting.

sl_hal_sysrtc_disable#

void sl_hal_sysrtc_disable (void )

Disables SYSRTC counting.

SL_CODE_CLASSIFY#

SL_CODE_CLASSIFY (SL_CODE_COMPONENT_PERIPHERAL_SYSRTC , SL_CODE_CLASS_TIME_CRITICAL , group_number, flags, group_number, flags)

Waits for the SYSRTC to complete all synchronization of register changes and commands.

Gets SYSRTC input capture register value for capture channel of given group.

Sets SYSRTC compare register value for selected channel of given group.

Gets SYSRTC compare register value for selected channel of given group.

Gets pending SYSRTC interrupt flags for the given group.

Clears one or more pending SYSRTC interrupts for the given group.

Disables one or more SYSRTC interrupts for the given group.

Enables one or more SYSRTC interrupts for the given group.

Gets SYSRTC counter value.

Returns

• Current SYSRTC counter value.

Note

• Depending on the use, a pending interrupt may already be set prior to enabling the interrupt. To ignore a pending interrupt, consider using sl_hal_sysrtc_clear_group_interrupts() prior to enabling the interrupt.

Note

• Event bits are not cleared by using this function.

Returns

• Pending SYSRTC interrupt sources. Returns a set of interrupt flags OR-ed together for multiple interrupt sources in the SYSRTC group.

Returns

• Compare register value.

Returns

• Capture register value.

sl_hal_sysrtc_wait_ready#

void sl_hal_sysrtc_wait_ready (void )

Waits for the SYSRTC to complete reseting or disabling procedure.

sl_hal_sysrtc_start#

void sl_hal_sysrtc_start (void )

Starts SYSRTC counter.

This function will send a start command to the SYSRTC peripheral. The SYSRTC peripheral will use some LF clock ticks before the command is executed. The sl_hal_sysrtc_wait_sync() function can be used to wait for the start command to be executed.

Note

• This function requires the SYSRTC to be enabled.

sl_hal_sysrtc_stop#

void sl_hal_sysrtc_stop (void )

Stops the SYSRTC counter.

This function will send a stop command to the SYSRTC peripheral. The SYSRTC peripheral will use some LF clock ticks before the command is executed. The sl_hal_sysrtc_wait_sync() function can be used to wait for the stop command to be executed.

Note

• This function requires the SYSRTC to be enabled.

sl_hal_sysrtc_reset#

void sl_hal_sysrtc_reset (void )

Restores SYSRTC to its reset state.

sl_hal_sysrtc_get_status#

uint32_t sl_hal_sysrtc_get_status (void )

Gets SYSRTC STATUS register value.

Returns

• Current STATUS register value.

sl_hal_sysrtc_lock#

void sl_hal_sysrtc_lock (void )

Locks SYSRTC registers.

Note

• When SYSRTC registers are locked SYSRTC_EN, SYSRTC_CFG, SYSRTC_CMD, SYSRTC_SWRST, SYSRTC_CNT and SYSRTC_TOPCNT registers cannot be written to.

sl_hal_sysrtc_unlock#

void sl_hal_sysrtc_unlock (void )

Unlocks SYSRTC registers.

Note

• When SYSRTC registers are locked SYSRTC_EN, SYSRTC_CFG, SYSRTC_CMD, SYSRTC_SWRST, SYSRTC_CNT and SYSRTC_TOPCNT registers cannot be written to.

sl_hal_sysrtc_set_counter#

void sl_hal_sysrtc_set_counter (uint32_t value)

Sets the SYSRTC counter value.

sl_hal_sysrtc_init_group#

void sl_hal_sysrtc_init_group (uint8_t group_number, sl_hal_sysrtc_group_config_t const * p_group_config)

Initializes the selected SYSRTC group.

sl_hal_sysrtc_get_group_enabled_interrupts#

uint32_t sl_hal_sysrtc_get_group_enabled_interrupts (uint8_t group_number)

Gets enabled and pending SYSRTC interrupt flags.

Useful for handling more interrupt sources in the same interrupt handler.

Note

• Interrupt flags are not cleared by using this function.

Returns

• Pending and enabled SYSRTC interrupt sources. The return value is the bitwise AND of

  • the enabled interrupt sources in SYSRTC_GRPx_IEN and

  • the pending interrupt flags SYSRTC_GRPx_IF.

sl_hal_sysrtc_set_group_interrupts#

void sl_hal_sysrtc_set_group_interrupts (uint8_t group_number, uint32_t flags)

Sets one or more pending SYSRTC interrupts for the given group from Software.
