Repeated START condition (Sr) to communicate to anoth-
er I²C slave. See Figure 21.
Slave Address
The MAX14830 includes a 7-bit I²C slave address, allowing
up to 16 MAX14830 devices to share the same I²C bus.
The address is defined by connecting the MOSI/A1 and CS/
A0 inputs to ground, V_L, SDA or to SCL (Table 12). Set the
read/write bit to 1 to configure the MAX14830 to read mode.
Set the read/write bit to 0 to configure the MAX14830 to
write mode. The address is the first byte of information sent
to the MAX14830 after the START condition.
