HB_PWM3 [2]
PWM mapping on HB3
This 3 bits register is used to indicate which PWM signal is applied to the HS or LS of the half-bridge 3
000 = LS of HB mapped on PWM1
001 = LS of HB mapped on PWM2
010 = LS of HB mapped on PWM3
011 = HS of HB mapped on PWM1
100 = HS of HB mapped on PWM2
101 = HS of HB mapped on PWM3
110 = 111 = No mapped

HB_MODE3 [1] HB3 functionality mode
00 = LS and HS of the HB3 are kept off
01 = LS of the HB3 is ON (static, no PWM), HS of the HB3 is OFF
10 = HS of the HB3 is ON (static, no PWM), LS of the HB3 is OFF
11 = LS or HS of the HB3 is ON in according to the HB_PWM1 register
