Data Sheet  
Table 13. Write and Read to RDAC and 50-TP memory  
DIN  
SDO1  
Action  
0x1C03 0xXXXX Enable update of wiper position and 50-TP memory contents through digital interface.  
0x0500 0x1C03 Write 0x100 to the RDAC register, wiper moves to ¼ full-scale position.  
0x0800 0x0500 Prepare data read from RDAC register.  
0x0C00 0x100  
Stores RDAC register content into 50-TP memory. 16-bit word appears out of SDO, where last 10-bits contain the  
contents of the RDAC Register 0x100.  
0x1800 0x0C00 Prepare data read of last programmed 50-TP memory monitor location.  
0x0000 0xXX19 NOP Instruction 0 sends a 16-bit word out of SDO, where the six LSBs last 6-bits contain the binary address of the last  
programmed 50-TP memory location, for example, 0x19 (see Table 16).  
0x1419 0x0000 Prepares data read from Memory Location 0x19.  
0x2000 0x0100 Prepare data read from the control register. Sends a 16-bit word out of SDO, where the last 10-bits contain the contents  
of Memory Location 0x19.  
0x0000 0xXXXX NOP Instruction 0 sends a 16-bit word out of SDO, where the last four bits contain the contents of the control register.  
If Bit C3 = 1, fuse program command successful.  
1 X is don’t care.

0 = 50-TP program disabled (default)  
1 = enable device for 50-TP program  
RDAC register write protect  
0 = wiper position frozen to value in 50-TP memory (default)1  
1 = allow update of wiper position through a digital interface  
Resistor performance enable  
0 = RDAC resistor tolerance calibration enabled (default)  
1 = RDAC resistor tolerance calibration disabled
