This section explains how to clear all parameters of an ACPU and explains
how to set the program capacity, file register capacity, etc.
Only those parameters that can be set by the A8PUE are given on the
parameter sheet attached to the APPENDIX. An A6GPP/A6PHP (SW
[ I ;
GP-
GPPA), IBM* PC/AT (SW;:;IX-GPPAE) and A7PHPE (SWi:; RX-GPPAE),
etc. are necessary for setting of other parameters.
Since this manual only explains parameter setting operations, determine the
setting contents of parameters by referring to the Programming Manual of the
particular ACPU.
The operation given below illustrates parameter setting.
