0x1400~0x1403 RPDO communication
Contains the communication parameters for the PDOs the device is able to receive. The

type of the PDO communication parameter (20h) is described in CiA 301 section 9.5.4. The

sub-index 0h contains the number of valid entries within the communication record. Its value

is at least 2. If inhibit time is supported, the value is 3. At sub-index 1h resides the COB-ID of

the PDO. This entry has been defined as UNSIGNED32 in order to allow 11-bit CAN Identifiers

(CAN 2.0A) as well as for 29-bit CAN identifiers (CAN 2.0B).
