Memory Read/Write - Ricoh Aficio 1013 Service Manual

5.1.12 MEMORY READ/WRITE

You can use SP7-955 to read byte values from arbitrary RAM addresses, and to
write values to arbitrary RAM addresses.
When you enter this SP, the screen looks likes this:
Mem R/W (1byte)
Adr=800000
You can now operate the SP as follows.
• To manually enter an address or data value: Use the cursor keys to move to the
desired column in the Adr field. Use numeric keys to input number values 1 to 9,
and [Original Type + numeric keys "1" to "6"] to input number values A to F.
• After entering an address value, press OK (or ') to set the value. The Data field
will then display the current content of the entered address. The cursor will jump
to the Data field.
• To increment or decrement the address, use the density keys (or Original Type +
cursor keys). The Data value will change to show the content of the selected
address.
• When the cursor is in the Data field, you can enter a new value to be stored into
the selected address. Press OK (or ') to write the new value into the address.
The cursor will then return to the Address field.
• If you are in the Data field, pressing Cancel will move you to the address field. If
you are in the address field, pressing Cancel will exit this SP.
• To cancel an entry in progress (and restore the previous value), press %. To
exit the SP, press the Clear Modes key.
