Serial Microcontroller Interface
The Serial Microcontroller Interface is used to access the SICOFI
4-μC
s internal
registers and the Coefficient RAM (CRAM). The Serial Microcontroller Interface consists
of four pins: two data pins (DIN, DOUT), one clock pin (DCLK) and one pin for chip select
(CS#). If DIN and DOUT are strapped together, only three microcontroller I/O pins are
required to build this interface.
