SERMODE
Serial-Interface Mode Input. When connected to GND, standard 3-wire
communication is selected. When connected to VCC, SPI communication is selected.
12
8
CE
Chip Enable. The chip-enable signal must be asserted high during a read or a write
for either 3-wire or SPI communications.
14
9
SCLK
Serial-Clock Input. SCLK is used to synchronize data movement on the serial
interface for either 3-wire or SPI communications.
15
10
SDI
Serial-Data Input. When SPI communication is selected, SDI is the serial-data input
for the SPI bus. When 3-wire communication is selected, this pin must be connected
to SDO (SDI and SDO function as a single I/O pin when connected together).
16
11
SDO
Serial-Data Output. When SPI communication is selected, SDO is the serial-data
output for the SPI bus. When 3-wire communication is selected, this pin must be
connected to SDI (SDI and SDO function as a single I/O pin when connected
together).
18
12
PF
Active-Low Power-Fail Output. The PF pin is used to indicate loss of the primary
power supply (VCC). When VCC is less than VPF, the PF pin is driven low.
