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 ad-
dress 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 al-
ready 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. How-
ever, the message uses same template, and accordingly ex-
change Address and Data when reading. The following dis-
play, for example,
