Command Byte
Use the command byte to select the destination of the
wiper data (nonvolatile or volatile memory registers)
and swap data between nonvolatile and volatile memo-
ry registers (see Table 2).
Data Byte
The MAX5432–MAX5435 use the first 5 bits (MSBs,
D7–D3) of the data byte to set the position of the wiper.
The last 3 bits (D2, D1, and D0) are don’t care bits (see
Table 2).
Command Descriptions
VREG: The data byte writes to the volatile memory reg-
ister and the wiper position updates with the data in the
volatile memory register.
NVREG: The data byte writes to the nonvolatile memory
register. The wiper position is unchanged.
NVREGxVREG: Data transfers from the nonvolatile
memory register to the volatile memory register (wiper
position updates).
VREGxNVREG: Data transfers from the volatile memory
register into the nonvolatile memory register.
