7.61. Reg : 64H (Write)

Defalut : 00H

PHFREQ[7:0]: to set PWM frequency for motor phase of uni-polar.

Frequency : (24MHz)/[(PHFREQ+1)*4

7.62. Reg :65H (Write)

Defalut : 3FH

MTRPWM[5:0]: to set PWM duty cycle for table one motor phase of uni-polar.

MTRPWM = 0 1/64 duty

= 1 2/64 duty

= 2 3/64 duty

……

= 63 64/64 duty
