FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Analog Die System Trim Values
For improved application performance, and to ensure the
outlined datasheet values, the analog die needs to be
trimmed. For this purpose, 3 trim values are stored in the
Flash memory at addresses $FDC4 - $FDC6. These values
have to be copied into the analog die SPI registers:
copy $FDC4 into SYSTRIM1 register $0F
copy $FDC5 into SYSTRIM2 register $10
copy $FDC6 into SYSTRIM3 register $11
Note: These values must be copied to the respective SPI
register after a reset, to ensure proper trimming of the device.
System Test Register (SYSTEST)
The System Test Register is reserved for production
testing and is not allowed to be written to.
System Trim Register 1 (SYSTRIM1)
HVDDT1:0 - HVDD Over-current Shutdown Delay Bits
These read/write bits allow changes to the filter time (for
capacitive load) for HVDD over-current detection. Reset
clears the HVDDT1:0 bits and sets the delay to the maximum
value.
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.
