9.2 Reading from the CPU Shared Memory of another CPU
9.2.1 Reading from Other CPU Shared Memory (FROM(P), DFRO(P))
(a) CPU shared memory address of the Basic model QCPU
(b) CPU shared memory address of the Universal model QCPU
*3
*2 : Usable as a user free area when auto refresh setting is not made.
When auto refresh setting is made, the auto refresh send range and later are usable as a user
free area.
*3 : With Q02UCPU, data can not be written to the multiple CPU high speed transmission area.
(2) When 0 is specified in n3 as the number of data to be read, no processing is performed.
(3) The number of data to be read changes depending on the target CPU module.
DFRO
(1) Reads the data of (n3×2) words from the CPU shared memory address designated by n2 of
the CPU module designated by n1, and stores that data into the area starting from the
device designated by .
