FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
ITRIM3:0 - IRef Trim Bits
These write only bits are for trimming the internal current
references IRef (also A0, A0CST). The provided trim
values have to be copied into these bits after every reset.
Reset clears the ITRIM3:0 bits.
System Trim Register 2 (SYSTRIM2)
CRHBHC1:0 - Current Recopy HB1:2 Trim Bits
These write only bits are for trimming the current recopy
of the half-bridge HB1 and HB2 (CSA=0). The provided
trim values have to be copied into these bits after every
reset. Reset clears the CRHBHC1:0 bits.
CRHB5:3 - Current Recopy HB3:4 Trim Bits
These write only bits are for trimming 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.
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.
