CRHB5:3 - Current Recopy HB3:4 Trim Bits
These write only bits are for trimming of the current
recopy of the half-bridge HB3 and HB4 (CSA=1). The
provided trim values have to be copied into these bits
after every reset. Reset clears the CRHB5:3 bits.
Table 18. Current Recopy Trim for HB3:4 (CSA=1)
CRHB2:0 - Current Recopy HB1:2 Trim Bits
These write only bits are for trimming of the current
recopy of the half-bridge HB1 and HB2 (CSA=1). The
provided trim values have to be copied into these bits
after every reset. Reset clears the CRHB2:0 bits.

System Trim Register 3 (SYSTRIM3)
CRHBHC3:2 - Current Recopy HB3:4 Trim Bits
These write only bits are for trimming of the current
recopy of the half-bridge HB3 and HB4 (CSA=0). The
provided trim values have to be copied into these bits
after every reset. Reset clears the CRHBHC3:2 bits.
Table 20. Current Recopy Trim for HB3:4 (CSA=0)
CRHS5:3 - Current Recopy HS2:3 Trim Bits
These write only bits are for trimming of the current
recopy of the high-side HS2 and HS3. The provided trim
values have to be copied into these bits after every reset.
Reset clears the CRHS5:3 bits.
