Table 7
To check the proper function of the serial interface the TLE6240GP provides a “SPI Echo Function”. By entering
HLHL as control word, SI and SO are connected during the next CS period. By comparing the bits clocked in with
the serial output bits, the proper function of the SPI interface can be verified. This internal loop is only closed
once (for one CS period). The “Echo Function” does not cause any internal processing of data and after the next
CS signal the SO data is ‘0’ (all registers reset).

Table 8
With LLHH LLLL as the control word, each of the input signals IN1 to IN4 are ‘OR’ed with the corresponding SI
data bits.
With LLHH HHHH as the control word, each of the input signals IN9 to IN12 are ‘OR’ed with the corresponding SI
data bits.
