ABSTRACT:
A polling device of the present invention performs communication control such that frame synchronous transfer modes and frame asynchronous transfer modes are used so as to perform a communication operation, and includes: a polling counter section for reading all communication channels for each address number; a state circuit for changing the order of priority in transfer each time the polling counter section counts one round of values after initializing the state circuit for each frame period; a latch section for latching a value of the polling counter section; and a matching detection section for comparing the value latched by the latch section with a value of the polling counter section, in which a polling operation is started from the value latched by the latch section at the time of initializing the state circuit for each frame period.
