7.16 Fast serial bus and registers
7.16.1 Fast serial bus description
The fast serial bus interface has three lines: a data line SIDA, a clock line SICL and a
strobe line SILD. The bus circuitry consists of a serial input shift register and several
registers that store the data. During a transmission the data is rst clocked into the shift
register. On the rising edge of SILD the contents of the input register are copied into the
addressed register. From that moment the programmed settings become effective. As
long as SILD is HIGH, the TZA1047 will not respond to SIDA and SICL. Examples of
one-word and two-word transmissions are shown in Figure 26 and Figure 27.
