3.1.2 Clear MMA Function

This function clears the MMA internal states so that another round of testing can be prepared.

void clear_mma(void)
{
     __HWA_CONFIG_REG_v1 mma_config_reg;
     mma_config_reg = __gen_HWA_CONFIG_REG_v1();
     mma_config_reg.PARITYCTRL = __MMA_NORMAL;
     __HWA_OFFSET_REG offset_reg;
     offset_reg = __gen_HWA_OFFSET_REG();
     __HWAOPEN(mma_config_reg,offset_reg,__MMA_OPEN_FSM_RESET);
     __HWAADV();
     __HWAADV();
     __HWAADV();
     __HWAADV();
     __HWACLOSE(0); //Clearing the first error code
}
