X is don’t care.
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.

Action
Enable update of wiper position and 50-TP memory contents through digital interface.
Write 0x100 to the RDAC register, wiper moves to ¼ full-scale position.
Prepare data read from RDAC register.
Stores RDAC register content into 50-TP memory. 16-bit word appears out of SDO, where the last 10-bits contain the
contents of the RDAC Register 0x100.
Prepare data read of the last programmed 50-TP memory monitor location.
NOP Instruction 0 sends a 16-bit word out of SDO, where the six LSBs (that is, the last 6 bits) contain the binary address
of the last programmed 50-TP memory location, for example, 0x19 (see Table 11).
Prepares data read from Memory Location 0x19.
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.
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 C2 = 1, fuse program command successful.
Description
50-TP program enable
0 = 50-TP program disabled (default)
1 = enable device for 50-TP program
RDAC register write protect
0 = wiper position frozen to value in OTP memory (default)
1 = allow update of wiper position through a digital interface
50-TP memory program success bit
0 = fuse program command unsuccessful (default)
1 = fuse program command successful
