Register Map Summary
Register Type Definition
Conexant Proprietary and Confidential Information
Most of the register set resides on the APB. These registers are accessible by the
microcontroller directly (memory-mapped). They are also accessible by the host slave-
mode interface indirectly (host pointer).
The register types are defined in Table 14-1.
All registers are not pre-fetchable, which would imply side effects from reads. This
means that read or write accesses, sequential or not, may drive state-dependent state
control.
