Storing RAM Data
PCU operation is based on the parameters and positioning actions contained
in RAM. When power is turned on, the data in EEPROM is read into RAM.
The data in RAM can then be changed by transferring data with WRIT(87) or
from the Teaching Box. This data will be deleted and replaced by EEPROM
data the next time power is turned off and back on. There is a command
available, however, to write RAM data to EEPROM (STORE), as well as one
to restore EEPROM data to RAM (RESTR). These commands can be used
along with WRIT(88) (or the Teaching Box) to control the data in RAM. This
situation is illustrated below.
