In the DC specification the supply current is
given for different modes of operation.
The AC power component gives the PLD,
Flash memory, and SRAM mA/MHz
specification. Figures
mA/MHz as a function of the number of
Product Terms (PT) used.
In the PLD timing parameters, add the
required delay when Turbo Bit is '0.'
