• Manufacturer Part Number: TLE7209-2R_07
• Description: 7 A H-Bridge for DC-Motor Applications
• Manufacturer: INFINEON [Infineon Technologies AG]

2.4.2.3
The 16 input bits consist of the SPI-instruction byte and a second, unused byte. The 16
output bits consist of the verification-byte and the data-byte (see also Figure 8). The
definition of these bytes is given in the subsequent sections.
Figure 8
2.4.2.4
The uppermost 2 bit of the instruction byte contain the chip-address. The chip-address
of the TLE 7209-2R is 00. During read-access, the output data according to the register
requested in the instruction byte are applied to SDO within the same SPI frame. That
means, the output data corresponding to an instruction byte sent during one SPI frame
are transmitted to SDO during the same SPI frame.
