CheckSum Bit (VOUT Register Only)

The CheckSum bit should be set by the Master controller to be the exclusive-NOR of the D[6:0] bits (odd parity).

This will be used by the TPS56X20 to check that a valid data byte was received. If CheckSum is not equal to the

exclusive-NOR of these bits, the TPS56X20 assumes that an error occurred during the data transmission, and it

will not send an ACK bit, nor will it reset the VOUT to the received code (or, if the Control register, will not reset

the register contents as requested). The Master should try again to send the data. When reading back the VOUT
