NOTE
Each bit in bit-band region has an equivalent bit that can be
manipulated through bit 0 in a corresponding long word in the
alias bit-band region.
13.5 Peripheral memory map
The peripheral memory map is accessible via a crossbar slave port and the AIPS
peripheral bridge. The peripheral bridge converts register access from AHB bus domain
to peripheral bus domain.
For peripherals that have clock gating control bits (CGC bit) in PCC module, the
associated peripherals could be enabled/disabled by these control bits. Access to a
disabled peripheral or unimplemented AIPS slot results in a transfer error termination.
For programming model accesses via the peripheral bridges, there is generally only a
small range within the 4 KB slots that is implemented. Accessing an address that is not
implemented in the peripheral results in a transfer error termination.
