Comment
1 Reset default for CHOPCONF.4 (hstrt0);
(pwm_autograd=1)
Depending on otp_en_SpreadCycle
0 Reset default for PWM_GRAD as defined by (0..15):
0: PWM_GRAD= 14
1: PWM_GRAD= 16
2: PWM_GRAD= 18
3: PWM_GRAD= 21
4: PWM_GRAD= 24
5: PWM_GRAD= 27
6: PWM_GRAD= 31
7: PWM_GRAD= 35
8: PWM_GRAD= 40
9: PWM_GRAD= 46
10: PWM_GRAD= 52
11: PWM_GRAD= 59
12: PWM_GRAD= 67
13: PWM_GRAD= 77
14: PWM_GRAD= 88
15: PWM_GRAD= 100
1 Reset default for CHOPCONF.0 to CHOPCONF.3 (TOFF)
Reset default for TBL:
0: TBL=%10
1: TBL=%01
Reset default for GCONF.internal_Rsense
0: External sense resistors
1: Internal sense resistors
Reset default for OTTRIM:
0: OTTRIM= %00 (143°C)
1: OTTRIM= %01 (150°C)
(internal power stage temperature about 10°C above the
sensor temperature limit)
Reset default for FCLKTRIM
0: lowest frequency setting
31: highest frequency setting
Attention: This value is pre-programmed by factory clock
trimming to the default clock frequency of 12MHz and
differs between individual ICs! It should not be altered.
