About us
At a Glance
This section presents the explicit exchange objects for the T_Unsigned_CPT_BMX and T_Signed_CPT_BMX- types IODDTs which are applicable to all BMX EHC •••• counting modules. They includes word type objects whose bits have a specific meaning. These objects are described in detail below.
Sample variable declaration: T_Unsigned_CPT_BMX and T_Signed_CPT_BMX-types IODDT_VAR1.
NOTE:
  • in general, the meaning of the bits is given for bit status 1.
  • not all bits are used.
