Decode PLD (DPLD)
The DPLD, shown in Figure 56,is used for decod-
ing theaddress for PSD Module and external com-
ponents. The DPLD can be used to generate the
following decode signals:
I
8 Sector Select (FS0-FS7) signals for the
primary Flash memory (three product terms
each)
I
4 Sector Select (CSBOOT0-CSBOOT3)signals
for the secondary Flash memory (three product
terms each)
I
1 internal SRAM Select (RS0) signal (two
product terms)
I
1 internalCSIOP Select signal(selectsthe PSD
Module registers)
I
1 JTAG Select signal (enables JTAG on Port C)
I
2 internal Peripheral Select signals
(Peripheral I/O mode).
