7.2.8
Programming the registers of TZA1038HW is done via a
serial bus (see Fig.7). The circuitry is formed by a serial
input shift register and a number of registers that store the
data. The registers can always be programmed,
irrespective of STANDBY mode.
If required, the bus lines can be connected in parallel with
an I
line during SICL = HIGH. This means that other I
devices will not recognise any START or STOP
commands. Control words addressed to TZA1038HW
7.3
The TZA1038HW is controlled by serial registers. To keep programming fast and efficient, the control bits are sent in
16-bit words. Four bits of the word are used for the address and for each address there are 12 data bits.

should go uniquely with the SILD signal. When
SILD = HIGH, the TZA1038HW will not respond to any
signal on SIDA or SICL.
During a transmission, the serial data is first stored in an
input shift register. At the rising edge of SILD, the content
of the input register is copied into the addressed register.
This is also the moment the programmed information
becomes effective.
The input pins have CMOS compatible threshold levels for
both 3.3 and 5 V supplies.
