Sony RM-PJM10, VPL-CX1 service manual Memory, Cpu Rom

3-6. Memory

Memory structure of VPL-CS2/CX1 series is based on the VPL-CS1 and it is composed of the following eight memory blocks.

1.Set memory

2.Status memory

3.Channel memory

4.Chroma memory

5.W/B memory

6.Reso memory

7.Gamma memory

8.Uniformity memory

CPU internal ROM : 256 kbyte Flash Memory

CPU internal ROM : 16 kbyte

External NVM memory : 8 kbyte EEPROM (BA mounted IC202)

When the power plug is connected to the power line (Standby status), all data inside the internal ROM are

written into the NVM (Nonvolatile Memory). When the power is turned to on, required data for the current picture, such as status memory data, etc., are selected, and they are written into the internal RAM. At this time, the gamma memory data and uniformity memory data which newly provided in this series are not writing into the internal RAM but they will be transferred to the register inside the device directly.

When adjustment is carried out, adjustment data are written into the NVM automatically (items on the user mode) or by the trigger of memory operation (items on the service mode and special service mode).

But, each values of gamma memory and uniformity memory does not adjust from the OSD but can only adjust by the RS232C communications.

Adjustable items (W/B and Device Adjust) of the service mode and special service are memorized into the NVM by the memory operation. At the same time, the factory preset (adjusted) data are all eliminated from the memory.
