(INCLUDING

SCOPE AND JIG

CAPACITANCE)

Upon delivery from ST, the PSD4000 device has all bits in the PLDs and memories in the

“1” or high state. The configuration bits are in the “0” or low state. The code, configuration,

and PLDs logic are loaded through the procedure of programming.

Information for programming the device is available directly from ST. Please contact your

local sales representative. (See the last page.)
