Both AR and HR areas
The following procedure is used to clear memory completely.
It is possible to retain the data in specified areas or part of the Program
Memory. To retain the data in the HR and AR, TC, and/or DM areas, press
the appropriate key after entering REC/RESET. HR is pressed to designate
both the HR and AR areas. In other words, specifying that HR is to be re-
tained will ensure that AR is retained also. If not specified for retention, both
areas will be cleared. CNT is used for the entire TC area. The display will
show those areas that will be cleared.
It is also possible to retain a portion of the Program Memory from the begin-
ning to a specified address. After designating the data areas to be retained,
specify the first Program Memory address to be cleared. For example, to
leave addresses 00000 to 00122 untouched, but to clear addresses from
00123 to the end of Program Memory, input 00123.
