DETAILED OPERATION
As shown in Figure 4, the PSD consists of six ma-
jor types of functional blocks:
I
Memory Blocks
I
PLD Blocks
I
MCU Bus Interface
I
I/O Ports
I
Power Management Unit (PMU)
I
JTAG-ISP Interface
The functions of each block are described in the
following sections. Many of the blocks perform
multiple functions, and are user configurable.
Memory Blocks
The PSD has the following memory blocks:
– Primary Flash memory
– Secondary Flash memory
– SRAM
The Memory Select signals for these blocks origi-
nate from the Decode PLD (DPLD) and are user-
defined in PSDsoft Express.
Table 28 sumamarizes the sizes and organisa-
tions of the memory blocks.
