Table 13. Write and Read to RDAC and 50-TP memory
DIN
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 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.

Bit Name
Description
C0
50-TP program enable
0 = 50-TP program disabled (default)
1 = enable device for 50-TP program
C1
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
C2
Resistor performance enable
0 = RDAC resistor tolerance calibration enabled (default)
1 = RDAC resistor tolerance calibration disabled
C3
50-TP memory program success bit
0 = fuse program command unsuccessful (default)
1 = fuse program command successful
1 Wiper position is frozen to the last value programmed in the 50-TP memory. Wiper freezes to midscale if 50-TP memory has not been previously programmed.
