 Power Down and Reset Timing
Following are issues concerning the parameters presented:
J
 In the DC specification the supply current is given for different modes of operation. 
Before calculating the total power consumption, determine the percentage of time that 
the PSD9XX is in each mode. Also, the supply power is considerably different if the 
Turbo bit is "OFF".
J
 The AC power component gives the PLD, Flash memory, and SRAM mA/MHz 
specification. Figures 27 and 27a show the PLD mA/MHz as a function of the number 
of Product Terms (PT) used.
J
 In the PLD timing parameters, add the required delay when Turbo bit is "OFF".
