B.5.2.1.2. AHB

The data slave interface is throttled as the read or write burst is carried out. The latency is designed to be as small as possible and is kept to a minimum when the use of XIP read instructions are enabled.

Software, using the documented programming interface, triggers FLASH erase operations, which may be required before a page write.

Once a page program cycle has been started, the QSPI Flash Controller automatically polls for the write cycle to complete before allowing any further data slave interface accesses to complete. This is achieved by holding any subsequent AHB direct accesses in wait state.
