Note:
Current profile has to pre set with I4 I3 I2 I1 I0 = 11111 and load to register 1.
Output current limit IQxnLIM is product of full scale current |IQxnFS_ | (bits DC2 DC1 DC0) and
value of DAC Phase A/B (bits I4 I3 I2 I1 I0) in register1.
Values of DAC Phase A and B can read out and depends on set up done before:
1.
direction DIR, stepping mode ST1 ST0 and phase counter P4 P3 P2 P1 P0 in register 0 and
2.
value of corresponding current profile (for address of current profile entry see also
Figure 3).
