0 = Direct PWM mode (Table 1)
1 = Control mode of Table 2 (All channels)
0 = H-Bridge mode
1 = STM µStep mode (*)
0 = Constant-current control disabled
1 = Constant-current control enabled (Channels A, B, C, D
and E)
* Valid only in H-Bridge mode (stmx = 0). Constant-current
control is always enabled in STM µStep mode.
0 = 0.075 V; 1 = 0.15 V; 2 = 0.225 V; 3 = 0.3 V
4 levels in 0.075-V steps (*)
Divides the external MCK by 1 to 31. (*, channel E)
0 = µStep mode with 6-bit resolution
1 = 1-2-phase excitation mode (*)
