manufacturing information.
Rotary Switch
The 16-position rotary switch (SW2) is wired to the MAX
II CPLD EPM2210 System
Controller. This rotary switch serves the following purposes:
■
At power up or when the reset configuration push-button switch (S1) is pressed,
this switch selects either the factory (page 0) or the user (page 1) design to load
into the FPGA.
■
After power up, the rotary switch selects the power rail monitored from among a
total of 16 rails. The power information is displayed in the Power GUI on a host PC
with a USB connection to the board.
■
User applications can obtain the switch value by reading the
rsr
register over the
FSM bus in the MAX
II CPLD EPM2210 System Controller.
Table 2–18
lists the power rails that are measured based on the rotary switch position.
