MAX14830
Quad Serial UART with 128-Word FIFOs
and Internal Oscillator
60
issuing a STOP condition (P), to relinquish control of the
bus, or a Repeated START condition (Sr) to communi-
cate to another I2C slave. See Figure 21.
Slave Address
The MAX14830 includes a 7-bit I2C slave address, allow-
ing up to 16 MAX14830 devices to share the same I2C
bus. The first 5 bits (MSBs) of the slave address are
factory programmed and are predefined for each of the
four UARTs (UART0, UART1, UART2, and UART3). The
two LSBs of the address are defined by connecting the
MOSI/A1 and CS/A0 inputs to ground, VL, 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.
