XMC4200 PSRAM Mapping

We're using the XMC4200 and look to be running into size constraints with the memory. Looking at Memory Settings page in DAVE it shows:

Name Type Start Address End Address Size
PSRAM1 RAM 0x1FFFE000 0x1FFFFFFF 0x2000
DSRAM1 RAM 0x20000000 0x20005FFF 0x6000

So PSRAM1 is 8KB and DSRAM1 is 24KB. We're supposed to have 40KB total and expecting 16KB on PSRAM1 but total is only 32KB.

Can we change the PSRAM1 size to 16KB and if so, what is the addressing we should use?

We notice the DSRAM1 addressing is consecutive with the PSRAM1 addressing so assume we need to change addressing for both.

Thanks
