Set pin of the SCK clock edge.
When this pin is “L” level, rising edge is available for input(SI) and falling
edge is available for output(SO).
When this pin is “H” level, falling edge is available for input(SI) and rising
edge is available for output(SO).
Chip select pin.
At the “L” level, data input/output is available.
Synchronous clock input pin for serial interface.
Input pin of synchronous serial data.
When the DIPH pin is “L” level, data is shifted in at the rising edges of
the SCK clock pulses.
When the DIPH pin is “H” level, data is shifted in at the falling edges of
the SCK clock pulses.
Output pin of synchronous serial data.
When the DIPH pin is “L” level, data is output at the falling edges of the
SCK clock pulses.
When the DIPH pin is “H” level, data is output at the rising edges of the
SCK clock pulses.
When the CSB pin is “H” level, this pin is Hi-Z state.
Set pin of the slave address.
Clock input pin for I2C serial interface.
This pin should be connected to pull-up resistor.
Input/output pin for I2C serial data.
Use for setting the mode of write/read and writing address, writing data
or reading data.
This pin should be connected to pull-up resistor.
(N-ch MOS) open drain, when output mode.
High impedance(Hi-Z), when input mode.
