Chapter 2 256 Kbyte Flash Module (FTS256K2V1)
2.8
The Flash module can generate an interrupt when all Flash command operations have completed, when
the Flash address, data, and command buffers are empty.
2.8.1
The logic used for generating interrupts is shown in
The Flash module uses the CBEIF and CCIF flags in combination with the CBIE and CCIE enable bits to
generate the Flash command interrupt request.
