(described later).
Before starting the test, all addresses of RAM (IC303) are
cleared to 0x0000. First, 0xA55A is written to the address
0x00000, and the address data are read and checked from
addresses 0x00001 to 0x80000 while shifting 1 bit each.
Next, the data at that address is cleared, and it is written
to the address 0x00001, and read and checked in the same
manner. This check is repeated up to the address 0x80000
while shifting the address data by 1 bit each.
If data other than 0 is read at the addresses except written
address, an error is given because all addresses were
already cleared to 0. In this check, the error display
pattern is different from that of other diagnosis; read data,
written address, and read address are displayed in this

these addresses are in the form of shadow. Also, if the
