Serial Control of the Outputs: SPI protocol
Each output is independently controlled by an output latch and a common reset line, which di s -
ables all four outputs. The Serial Input (SI) is read on the falling edge of the serial clock. A logic
high input 'data bit' turns the respective output channel ON, a logic low 'data bit' turns it OFF.
transfers the serial data input bits to the output control buffer.
As mentioned above, the serial input byte consists of a 4 bit control word and a 4 bit data word.
Via the control word, the specific mode of the device is programmable.
Five specific control words are recognised, having the following functions:
Note: 'X' means 'don't care', because this bit will be ignored
1. LLLL XXXX
By clocking in this control byte, it is possible to get pure diagnostic information (two bits per
channel) in accordance with Figure 1 (page 11). The data bits are ignored, so that the state of
the outputs are not influenced. This command is only active once unless the next control com-
mand is again "Diagnosis only".
2. HHLL XXXX
If the TLE 6220 GP is used as bare die in a hybrid application, it is necessary to know if proper
connections exist between the µC-port and parallel inputs. By entering ‘HHLL’ as the control
word, the first four bits of the SO give the state of the parallel inputs, depending on the µC si g -
nals. By comparing the four IN-bits with the corresponding µC-port signal, the necessary con-
nection between the µC and the TLE 6220 can be verified - i.e. ‘read back of the inputs’.
The second 4-bit word fed out at the serial output contains ‘1-bit’ fault information of the out-
puts ( H = no fault, L = fault ). In the expression given below for the output byte, ‘FX’ is the fault
bit for channel X.
