Data Fields
ra8_tsn_cal_temp_t	high_ref_degc
	105 or 125 degC.

	Always -40 degC on RA8D2.
uint16_t	stab_us
	tTSTBL in microseconds.

Detailed Description

Configuration descriptor for ra8_tsn_init.

• high_ref_degc selects which calibration temperature was used at factory shipment. Pass k_ra8_tsn_cal_temp_high_125 for Tj_max = 125 degC parts and k_ra8_tsn_cal_temp_high_105 for Tj_max = 95 / 105 degC parts (HUM Ch 55.3.1 p 3499-3500).
• low_ref_degc is always k_ra8_tsn_cal_temp_low_n40 for the RA8D2 family and is captured here so the conversion math stays self-documenting.
• stab_us is the busy-wait observed after asserting TSCR.TSEN before the sensor output is valid. HUM Figure 55.2 (p 3502) names this tTSTBL = 30 us; callers may bump the value to absorb extra slack on slow boards but must not go below 30.
