HLHL XXXX
- Echo-function of SPI
To check the proper function of the serial interface the TLE 6220 GP 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).

LLHH DDDD
- OR operation, and 鈥榝ull diagnosis鈥?/div>
With LLHH as the control word, each of the input signals IN1...IN4 are 'OR'ed with the corre-
sponding data bits (DDDD).

Driver
This OR operation enables the serial interface to switch the channel ON, even though the cor-
responding parallel input might be in the off state.
SPI Priority for ON-State
Also parallel control of the outputs is possible without an SPI input.
