Serial Interface
The FPGA provides routing options of one of the two serial interfaces provided by the
Southbridge. This feature is intended for Motorola−internal purposes and should be
ignored. .
a
Reset Mask and Source Register
The FPGA provides two registers which allow to obtain the last reset source and to mask
resets. See
a
section "Reset Registers" on page
a
Flash Control Register
The FPGA provides one register which allows to monitor the boot and user flash
write−protection status as well as to control the write−protection of the boot flash boot
block. See
section "Flash Control and Status Register" on page
PMC Status Register
The FPGA provides one register which allows to monitor the status of the four PMC sites.
See
a
section "PMC Status Register" on page
Shut−Down Register
The FPGA provides one register which allows to control the blades’ FRU−EN signal.

a
section "Shut Down Register" on page
LEDs
The FPGA provides a register to control the HDD LED available at the face plate. This
LED indicates the combined parallel and serial ATA activity or is operated in user LED
mode. See
a
section "LED Control Register" on page
a
Version Register
This register allows to obtain the current FPGA version. See
