Detailed Description

Configuration descriptor for ra8_gpt_three_phase_open.

Mirrors FSP three_phase_cfg_t from fsp/ra/fsp/inc/api/r_three_phase_api.h. The driver opens the three GPT channels listed in channels (typically GPT0/GPT1/GPT2) with a shared period_counts and identical base_cfg mode and prescaler so they form a phase-synchronized motor inverter. The three channels are armed via the same GTSTR write so they start on the same PCLKD edge.

Each member is read inside ra8_gpt_three_phase_open in libs/ra8_hal/src/ra8_gpt.c.
