NAME
FUNCTION
1
SPI/I2C
SPI or Active-Low I2C Selector Input. Drive SPI/I2C high to enable SPI. Drive SPI/I2C low to enable I2C.
2
LDOEN
LDO Enable Input. Drive LDOEN high to enable the internal 1.8V LDO. Drive LDOEN low to disable the
internal LDO. When LDOEN is low, V18 can be supplied by an external voltage source.
3
MISO/SDA Serial-Data Output. When SPI/I2C is high, MISO/SDA functions as the MISO, SPI serial-data output.
When SPI/I2C is low, MISO/SDA functions as the SDA, I2C serial-data input/output.
4
SCLK/SCL Serial-Clock Input. When SPI/I2C is high, SCLK/SCL functions as the SCLK, SPI serial-clock input (up
to 26MHz). When SPI/I2C is low, SCLK/SCL functions as the SCL, I2C serial-clock input (up to 1MHz).
5
CS/A0
Active-Low Chip-Select and Address 0 Input. When SPI/I2C is high, CS/A0 functions as the CS, SPI
active-low chip-select input. When SPI/I2C is low, CS/A0 functions as the A0, I2C device address pro-
gramming input. Connect CS/A0 to SDA, SCL, DGND, or VL when SPI/I2C is low.
6
MOSI/A1
Serial-Data and Address 1 Input. When SPI/I2C is high, MOSI/A1 functions as the MOSI, SPI serial-
data input. When SPI/I2C is low, MOSI/A1 functions as the A1, I2C device address programming input.
Connect MOSI/A1 to SDA, SCL, DGND, or VL when SPI/I2C is low.
7
IRQ
Active-Low Interrupt Open-Drain Output. IRQ is asserted when an interrupt is pending.
8
RST
Active-Low Reset Input. Drive RST low to force all of the UARTs into hardware reset mode. In hardware
reset mode, the oscillator and the internal PLL are shut down and there is no clock activity.
