NAME
FUNCTION
1
RST
Active-Low Reset Input. Drive RST low to force all of the UARTs into hardware reset mode. Driving RST
low also enables low-power shutdown mode. When RST is low, the internal V18 LDO is switched off,
even if the LDOEN input is kept high.
2
MISO/SDA
Serial-Data Output. When SPI/I2C is high, MISO/SDA functions as the SPI master input-slave output
(MISO). When SPI/I2C is low, MISO/SDA functions as the SDA, I2C serial-data input/output. MISO/SDA is
high impedance when RST is driven low or when the externally supplied V18 is powered off.
3
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 in fast
mode plus).
4
GPIO7
General-Purpose Input/Output 7. GPIO7 is user-programmable as an input or output (push-pull or open
drain) or an external event-driven interrupt source. GPIO7 has a weak pulldown resistor to DGND when
configured as an input.
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. When SPI/I2C is low, CS/A0 functions as the A0 I2C device address programming
input. Connect CS/A0 to DGND, VL, SCL, or SDA when SPI/I2C is low.
6
MOSI/A1
Serial-Data Input and Address 1 Input. When SPI/I2C is high, MOSI/A1 functions as the SPI master
output-slave input (MOSI). When SPI/I2C is low, MOSI/A1 functions as the A1 I2C device address
programming input. Connect MOSI/A1 to DGND, VL, SCL, or SDA when SPI/I2C is low.
7
IRQ
Active-Low Interrupt Open-Drain Output. IRQ is asserted when an interrupt is pending. IRQ is high
impedance when RST is driven low.
