Detailed Description

Absolute Memory-mapped IO functions, for volatile access.

Memory-mapped IO functions, which map to volatile accesses. Use this module for register operations in ROM and ROM Extension production libraries.

Compiling translation units that pull in this header with -DMOCK_ABS_MMIO will disable the definitions of abs_mmio_read and abs_mmio_write. These symbols can then be defined by a test harness to allow for instrumentation of MMIO accesses.
