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 have to 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 into.
System Trim Register 1 (SYSTRIM1)
HVDDT1:0 - HVDD Over-current Shutdown Delay Bits
These read/write bits allow changing the filter time (for
capacitive load) for the HVDD over-current detection.
Reset clears the HVDDT1:0 bits an sets the delay to the
maximum value.
Table 15. HVDD Over-current Shutdown Selection Bits
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.
