MAX V CPLD 5M2210 System Controller
The board utilizes the 5M2210 System Controller, an Altera MAX V CPLD, for the
following purposes:
■
FPGA configuration from flash
■
Power measurement
■
Control and status registers for remote system update
Figure 2–2
illustrates the MAX V CPLD 5M2210 System Controller's functionality and
external circuit connections as a block diagram.
Table 2–4
lists the I/O signals present on the MAX V CPLD 5M2210 System
Controller. The signal names and functions are relative to the MAX V device.
