A.2.6. HPS Use of SDM QSPI Controller Functional Description
The QSPI Flash controller uses the register target interface to select the operation modes and configure the data target interface for data transfers. The QSPI Flash controller uses the data target interface for direct and indirect accesses, and the register target interface for software triggered instruction generator (STIG) operation accesses.
Accesses to the data target are forwarded to the direct or indirect access controller. If the access address is within the configured indirect address range, the access is sent to the indirect access controller.
