Section 6 Interrupts

6.1 General

The FTS64K module can generate an interrupt when all Flash commands are completed or the address,

data and command buffers are empty.

NOTE

Vector addresses and their relative interrupt priority are determined at the MCU level

6.2 Description of Interrupt Operation

Figure 6-1 shows the logic used for generating interrupts.

This system uses the CBEIF and CCIF flags in combination with the enable bits CBIE and CCIE to

discriminate for the interrupt generation.
