6.4.3 MEMORY CLEAR
The basic machine (D170: the machine without the optional controller) stores all the data in the
NVRAM on the BICU. The data is cleared by SP5-801-002 (Memory Clear - Engine) (see
exceptions).
The GDI or GW+ machines (the machines with the optional controller) store the engine data in the
NVRAM on the BICU, and store the other data in the NVRAM on the optional controller. To
distinguish between the engine data and the other data, see SP5-801-003 through -024. This
service program (003-024) handles the controller data. Any data that is not handled by SP 5801 is
the engine data. The data in the BICU NVRAM (engine data) is cleared by SP5-801-002.
