Detailed Description

Port Output Enable for GPT (POEG) register layout for the RA8D2.

Four POEG groups (POEG0..POEG3) at 0x40212000 with 0x100 stride. Each group monitors one external emergency-stop input and, on trigger, forces the associated GPT outputs into a safe (high-impedance) state without CPU involvement. Essential for safety-critical motor control so an over-current fault can halt the H-bridges in a single cycle.
