Message Format for Writing
A write to the MAX5417/MAX5418/MAX5419 consists of
the transmission of the device’s slave address with the
8th bit set to zero, followed by at least 1 byte of infor-
mation (Figure 7). The 1st byte of information is the
command byte. The bytes received after the command
byte are the data bytes. The 1st data byte goes into the
internal register of the MAX5417/MAX5418/MAX5419 as
selected by the command byte (Figure 8).
Command Byte
Use the command byte to select the source and desti-
nation of the wiper data (nonvolatile or volatile memory
registers) and swap data between nonvolatile and
volatile memory registers (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 memo-
ry 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 memo-
ry register into the nonvolatile memory register.
