Notes:

1. All 16 data pins are persisted regardless of whether the SelectMAP data width is x8 or x16.

2. INIT_B is persisted if readback CRC is enabled, regardless of the POST_CRC_INIT_FLAG setting.

3. AWAKE and SCP[7:0] are activated based on the suspend setting.

4. A24 and A25 are in bank 5 in larger devices with 6 or more I/O banks.
