6.11.3. Width Adaptation

Platform Designer allows different data width connections with APB. When connecting a wider manager to a narrower APB subordinate, the width adapter converts the wider transactions to a narrower transaction to fit the APB subordinate data width. APB does not support Write Strobe. Therefore, when you connect a narrower transaction to a wider APB subordinate, the subordinate cannot determine which byte lane to write. In this case, the subordinate data may be overwritten or corrupted.
