Writing objects 0x1600:00 and 0x1A00:00 to 0 does not deactivate Tx / Rx PDO channels in the default mapping configuration

Objects 0x1600:00 and 0x1A00:00 have to be always defined as "read/write" even if running a static mapping configuration. When the stack is configured with default static mapping, the master is allowed to write value 0 to this objects. This should cause the deactivation of the corresponding PDO channel (Tx or Rx). However the deactivation is not processed. The new values are just stored in the local resources but never used.
