register (‘1’) is written to� During the SPI write cycle a byte o� data can be input to SPI Data In on the next clock cycle
a�ter the address bit�� MSB first� ��ter the data has been clocked in to the chip�� the status o� SPI Data Out should be
checked to see i� the data read was accepted� � ‘��’ level on SPI Data Out means that the data write was accepted� �
‘1’ indicates that the internal bu��er is �ull�� and the write should be repeated� Remember that CS must be held low �or at
least one cloc�� period before being ta��en high again to continue with the ne��t read or write cycle.
