scribed 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 order. However, the message
uses same template, and accordingly exchange Address and
Data when reading. The following display, for example,
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

than 0 is read at the addresses except written address, an

that of other diagnosis; read data, written address, and read
address are displayed in this order. However, the message
uses same template, and accordingly exchange Address and
Data when reading. The following display, for example,
shows the data 0xA55A was read from address 0x00080000
though it was written to the address 0x00000000. This im-
plies that these addresses are in the form of shadow. Also,
if the read data is not 0xA55A, another error will be present.
