14.5 Exempt_B Layout

The MAIN region (x) induces a single IDAU region (w). It is split into 32 equally sized blocks of 2^RSTA- TUSA[w].GRAN Bytes. Each block has its own NON-SEC bit mapped in RSTATUSB[w]. Only the first RSTATUSA[w].MAXSZ is configurable. RSTA-TUSB[x] is a constant 1 when 32<x<RSTATUSA[w].MAXSZ-1.

The size of the MAIN region is 2^IDAU_MAIN_REGIONS_MAP[x].decoding_size Bytes which must be greater than or equal to 32*2^RSTATUSA[w].GRAN Bytes.
