Figure 7. SPI Data/Clock Timing.
Serial Data Interface (SPI)
The serial data interface itself consists of the pins SCL (serial clock), SDI (serial data input) and SDO
(serial data output).
To especially support bus controlled applications the additional signals EN (chip enable not) and CSN
(chipselect not) areavailable.
Startup of the Serial Data Interface
Fallingslope of EN activatesthe device.After t
en.sck
the deviceis readyto work.
Falling slope of CSN indicates start of frame. Data transfer (reading SDI into the register) takes place at
the rising slopes of SCK.
Data transfer of the register to SDO takes place at the falling slope of SCK.
Rising slope of CSN indicates end of frame. At the end of frame data will only be accepted if modulo 8
bit (modulo8 falling slopes to SCK)have been transferred. If this is not the case the input will be ignored
and the bridges will maintain the same status as before.
SDO is a tristate output.
SDO is activewhile CSN = LOW,while CSN = HIGH SDO is high resistive.
