27
Data
Digital input
Serial address and data input pin. Address bits are followed by data bits.
28
CS
Digital input
Active low enable pin. Enables loading of address and data on the Data pin on the rising edge of Clock.
When CS goes high, data is transferred to the register indicated by the address. Subsequent clock edges
are ignored.
Note 1: Associated pairs of power and ground pins must be decoupled using 0.1
F capacitors.
