This is an example setup to perform the erase operation of the NOR type flash memory cell. To
perform the erase operation, all of the selector/ASU channels must make the path to the PG and the
PG3 internal pulse switch must be opened. The pulse switch is also a solid state relay.
Note that the solid state relay in the selector is not used. The relay must be always close.
