SPI access format:
Verification byte:
detected the data byte ’00h’ is transmitted to the controller after having sent the verification
byte (even if bit INSW afterwards is wrong) but modifications on any register of TLE6244 are
If an invalid instruction is detected bit TRANS_F in the following verification byte is set to
’High’. This bit must not be cleared before it has been sent to the microcontroller.
distinguished by the chip address (CPAD1, CPAD0). If an IC with 32bit-transmission-format is
selected, TLE6232 must not be activated, even if slave select is set to ’low’ and
the first two bits of the third byte of the 32bit-transmission are identical to the chip address
of TLE6244X.
During the transmission of CPAD1 and CPAD0 the data output SO remains in tristate (see
timing diagram of the SPI in chapter 3.9. ).
