7-6 Setting Cyclic Communications Range
Cyclic communications
The CM reads and writes data between the shared memory and the
MP2500 register, which is periodically set.
The communications by which the shared memory is periodically updated
is called cyclic communications.
By doing this, the shared memory always has the same values as the
selected MP2500 register.
For example, if allocating CW0 to CW9 and 1: MW0 to 1: MW9 for cyclic
communications, the value of CW0 is rewritten to 1: MW0
If the value of CW9 is changed, the value of 1: MW9 is rewritten to CW9.
