1. SRAM / SDRAM / FLASH test SRAM / SDRAM / FLASH Tests
Tests can be started by pressing the OK button.
SRAM: Device and bus tests are conducted to all areas of the SRAM.
Data is protected during the test.
SDRAM: Device and bus tests are conducted to all areas of the SDRAM, by
dividing the areas into BIOS / USER areas. During the device tests,
data in the BIOS area is not protected, while the data in the USER
area is protected During the bus test, data patterns are written in the
USER area, therefore, the data in the USER area is not protected.
FLASH: The CRC-CCITT codes are calculated from all areas within the range
specified by the ROM, and are verified to match with the code values
stored in the ROM.
