The functional silicon revision - this tracks changes in
functionality which are separate from ROM mask
settings
The state of the configuration pins. This selects what
register defaults should be.
DEFAULT
Indicates whether the system is on or off. Writing 0
to this bit powers down the whole chip. Registers
which are affected by state machine reset will get
reset.
Once the system is turned OFF it can be restarted
by any of the valid ON event.
Reset by state machine. Default held in metal
mask.
Allows the processors to reboot itself
0 = Do nothing
1 = Perform a processor reset by asserting the
/RST and /MEMRST (GPIO) pins for the
programmed duration
Protected by security key. Reset by state machine.
Default held in metal mask.
Action to take on a fault (if response is set to
shutdown system):
0 = Shut down
1 = Shutdown everything then go through startup
sequence. i.e. Reboot the system.
Include over voltage in the /VCC_FAULT pin
(Alternative GPIO function)
0 = Do not include over voltage in the
/VCC_FAULT signal
1 = Include the over voltage in the /VCC_FAULT
signal
Reset by state machine. Default held in metal
