This section describes the specifications, handling instructions and installation of
the memory ICs used in the AnSHCPU.
Table 7.1 and 7.2 show the specifications of the ROMs.
A1SNMCA-2KE *1
8 k bytes (max. 2 k steps)

Table 7.2 Memory specifications (A2SHCPU)
POINT
*1: When writing a program to the A1SNMCA-2KE,set the parameter for
main sequence program capacity to 2k steps or less.
Programs written with a main sequence program capacity setting of 3k
steps or over cannot work properly.
Checking between the AnSHCPU and a peripheral device will result in a
mismatch.
