FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
CRHB2:0 - Current Recopy HB1:2 Trim Bits
These write only bits are for trimming 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 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.
Current Recopy Trim for HB3:4 (CSA=0)
CRHS5:3 - Current Recopy HS2:3 Trim Bits
These write only bits are for trimming 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.
CRHS2:0 - Current Recopy HS1 Trim Bits
These write only bits are for trimming the current recopy of
the high side HS1. The provided Trim values have to be
copied into these bits after every reset. Reset clears the
CRHS2:0 bits.
