mode, RAM check is simplified. In concrete, only the skipped
blocks such as 0-ff, 500-5ff, a00-aff, f00-fff, 1400-14ff, ... (ad-
dresses) are checked. Check is executed from the top item of the
diagnosis check items list sequentially. In a checking where visual
check is not necessary, check progresses to the next item auto-
matically unless an error occurs.
In case of an error or visual check is necessary, press [PREV] key,
and the item concerned is repeatedly checked. To go to the next

(2-2) Syscon ROM (IC803) Check
Checksum calculation
Error: Not detected
At addresses from 0x00000 to 0xfffff of Syscon ROM (IC803),
checksum is calculated by adding 8-bit data, and the result is dis-
played with 4-digit number in hexadecimal notation. As the error
is not detected, compare the displayed result with original ROM
checksum.

Syscon RAM (IC802) matching check
Error 05: Write/read data mismatch error
External RAM (IC802) of IC805 (Syscon) is saved in the stack by
256 bytes each, and ROM data are transferred to the DMA. Then,
the data are compared with ROM (IC803) data every byte. In de-
tail check, the bit inverted data are further written, and rechecked.
During checking, all interruptions are stopped. Also, variables use
only the stacks including save area and bit inverted buffer. As a
processing is executed in the closed circuits within this function,
the data transfer to stack area also uses the DMA. In the detail
check, all areas of external RAM (IC802) are checked twice by
inverting the data, but in the simple check, one block is checked,
then the subsequent 4 blocks are skipped, and also a check of in-
verted data is not executed.
If write/read mismatch error occurred, checking can be repeated.

16-bit data is written to the address 0 of EEPROM (IC801), and it
is read to check for matching. Before checking, the content of ad-
dress 0 is read for saving, but if it cannot be read, the error is
displayed and operation is terminated, and data writing is not ex-
ecuted.
In this diagnosis, 16-bit data is checked. 16 kinds of patterns are
written by shifting 1 bit each from 0x0001 toward the left.
If write/read mismatch error occurred, checking can be repeated.
Even if an error occurs after write/read check started, the saved
data are written when this diagnosis is quitted, but whether data
are written correctly is not guaranteed.
