Number of words transferred:
Specify the total number of words to be written from the source node to the local
node in hexadecimal (0 to 3E8).
Operating Level:
Specify the operating level of the PC Card Unit
Response request bit:
Set this bit to 0 (OFF: response required) because the RECV(98) instruction
must return response data.
Indirect addressing bit for beginning source word:
Because CV-series PCs support larger areas than C-series PCs, the user may
not be able to specify the beginning source word of the source node in the
RECV(98) instruction operand. The beginning source word of the source node
may also need to be changed in some situations. In this case, set this bit to 1
(ON: indirect addressing). Then, the first operand (S) becomes an beginning
indirect source word, allowing the beginning source word (rightmost) at the
source node to be specified with the word specified for S in BCD format as
shown below.
