This should be seen in cooperation with zephyrproject-rtos/zephyr#72621

At the end, the erratum says: "reconfiguration of TWIM/SPIM is required before next usage" (the above link no longer works, this one can be used instead). Your implementation does not seem to be addressing this.

Anyway, anomaly 89 is already handled in another way. See:

	*(volatile uint32_t *)((uint8_t *)p_reg + 0x500UL) = 9;
	}
	#endif
