Detailed Description

CANFD Transmitter Delay Compensation (TDC) configuration.

Tag

[Ring 3 / HAL] {World: NS}

Single public entry-point: ra8_canfd_set_tdc – enables, configures, or disables the Transmitter Delay Compensation block in CFDCnFDCFG for one CANFD channel. The write is bracketed by CH_RESET / CH_OPERATION mode transitions using the shared helper priv_ra8_canfd_internal_set_channel_mode (promoted to TU-external linkage in ra8_hal_internal.h) – the same strategy used by ra8_canfd_set_bitrate in ra8_canfd_timing.c.

Every register access carries a HUM Ch 41 "CAN with Flexible Data-rate (CANFD)" citation (pages 2702..2867, chapter map row 41).
