Defalut : 00H,00H
GPO[12:7]
GPO[6:1]
7.64. Reg :68H,69H (Write)
Defalut : 00H,00H
GPOE[12:7]
GPOE[6:1]
Set ‘1’ : output.
Reset ‘0’ : input.
GPOM12~11 : to select GPIO12~11 as Bi-polar motor driver V-ref input voltage in
order to control drive current.
7.65. Reg :6AH (Write)
Defalut : 00H
FSTPSEL[1:0] : for table two fast moving step type selection.
(1).bi-polar :
a.00: full step.
b.01: half step.
c.10: quarter step.
d.11: reserved.
(2).uni-polar :
a.00: two-phase-on full step.
b.01: half step.
c.10: reserved.
d.11: single-phase-on full step.
FASTPWM[5:0]
: to set PWM duty cycle for table two motor phase of uni-polar.
FASTPWM =0 1/64 duty
=1 2/64 duty
=2 3/64 duty
……
=63 64/64 duty
note: If PHFREQ < 0FH,then PWM setting must < (PHFREQ+1)*4
7.66. Reg :6BH (Write)
Defalut : 00H
FMOVNO[7:0]: Set fast moving slop steps(table two slope).
note: If PHFREQ < 0FH,then PWM setting must < (PHFREQ+1)*4
: GPO12~7 outputs ports
: GPO6~1 outputs ports
: GPO12~7 ports output enable set.
: GPO6~1 ports output enable set.
