Detailed Description
Digital Serial Interface
An SPI-compatible serial interface controls the
MAX5408–MAX5411. The input word to the device is
eight bits long, composed of three address bits (A0,
A1, and A2), followed by five data bits, with MSB first
(see Tables 1 and 2). The first three address bits set
the value of internal registers. The five data bits control
the wiper position. For certain commands, some of the
five data bits are “don’t cares”, but must be sent to the
device.
The serial data is listed in Tables 1 and 2.
The control code determines:
Potentiometer to update or register to set.
Data for mute register (Tables 3 and 4).
Data for zero-crossing detection register (Tables 5
and 6).
The data bits control the position of the wiper (Table 7).
A logic low on the chip-select input (
CS) enables the
device’s serial interface. A logic high on
CS disables
the interface control circuitry. See Figure 1 for serial-
interface timing description.
