Special DR Register Function
If the special DR coil, DR65~DRF0, is used as a special register, it dose not need to be enabled; it works as
common register (it current value will equal to the preset value) once it is enabled.
The
DR65~DRF0 can retain the current value when stop or power down.
DRD0 ~ DRE3 as special registers used to set parameters, the output value function is as follows:
No.
