To limit the peak memory bandwidth generated by the IPIPEIF (read port), ISIF (read port), and H3A (write port) modules, a bandwidth limiter is placed between the modules and the BL. The RSZ module has this function built in and therefore does not need a bandwidth limiter.
The bandwidth limiter enables control of the minimum interval between two consecutive memory requests.
This function is controlled by the ISP5_BL_MTC_1 and ISP5_BL_MTC_2 registers. When the registers are set to 0, the function is not modified (that is, the bandwidth limiter is disabled). For the RSZ module, it is controlled by the RSZ_DMA_RZA and RSZ_DMA_RZB registers.
