PD_RESTORE
If a ‘0’ is set for Byte 0 bit 0 then, upon assertion of PWRDWN#
LOW, the CY505 will initiate a full reset. The results of this will
be that the clock chip will emulate a cold power on start and
go to the ‘Latches Open’ state. If the PD_RESTORE bit is set
to a ‘1’ then the configuration is stored upon PWRDWN#
asserted LOW. Note that if the iAMT bit, Byte 0 bit 3, is set to
a ‘1’ then the PD_RESTORE bit must be ignored. In other
words, in Intel iAMT mode, PWRDWN# reset is not allowed.
