HB_PWM2 [2]
PWM mapping on HB2
This 3 bits register is used to indicate which PWM signal is applied to the HS or LS of the Half-Bridge 2
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_MODE2 [1] HB2 functionality mode
00 = LS and HS of the HB2 are kept off
01 = LS of the HB2 is ON (static, no PWM), HS of the HB2 is OFF
10 = HS of the HB2 is ON (static, no PWM), LS of the HB2 is OFF
11 = LS or HS of the HB2 are ON according to the HB_PWM2 register
