[−][src]Module cc13x2_cc26x2_pac::aux_tdc
AUX Time To Digital Converter (AUX_TDC) is used to measure the time between two events with high resolution. AUX_TDC consists of a state machine that operates at AUX bus rate and an asynchronous fast-counter which is clocked by the TDC clock. DDI_0_OSC:CTL0.ACLK_TDC_SRC_SEL configures TDC clock source. The fast-counter counts on both edges of the TDC clock to double the resolution. See the Technical Reference Manual for event timing requirements.

ctl | Control |
precntr | Prescaler Counter |
prectl | Prescaler Control The prescaler can be used to count events that are faster than the AUX bus rate. It can be used to: - count pulses on a specified event from the asynchronous event bus. - prescale a specified event from the asynchronous event bus. To use the prescaler output as an event source in TDC measurements you must set both TRIGSRC.START_SRC and TRIGSRC.STOP_SRC to AUX_TDC_PRE. It is recommended to use the prescaler when the signal frequency to measure exceeds 1/10th of the AUX bus rate. |
