Programming
Upon delivery from ST, the PSD835G2 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.)
