2.8.2 NOR Flash

The SST25VF016 is a 2 MB NOR Flash, as shown in Figure 2-18. The PIC32 micro-

controller uses a SPI bus interface to communicate to the SST25VF016. The CPLD

needs to be properly configured for the PIC32 microcontroller to be able to access the

SST25VF016. For configuration information, see Section 2.12 “CPLD”.
