4.4.5.2
The PIC24FJ256DA210 Development Board has two external Flash memory devices.
Selection is controlled by jumper JP23. Only one can be enabled at any given time:
• 512 Kbyte Parallel Flash (SST39LF400A), connected to the EPMP port.
• 16 Mbits (2 Mbyte) SPI Serial Flash (SST25VF016B).
Flash memory configuration uses the same jumpers and resistors as SRAM configura-
tion (Figure 4-9). An additional jumper, JP23 (callout 1), selects between the serial and
parallel devices.
FIGURE 4-9:
4.4.5.2.1
To use the SPI Flash memory, set jumper JP23 to bridge pins 2 and 3 (PMCS2 – SPI).
The microcontroller’s SPI module is used to communicate with the memory device; the
PMCS2 signal is used as the Chip Select signal .
4.4.5.2.2
Like the SRAM, the on-board parallel Flash memory can be configured to use one of
three memory address ranges (shown in Table 4-8).
