Note that, in the Manchester coding used, a bit value of one is indicated by a falling edge within the bit boundary, and a bit value of zero is indicated by a rising edge within the bit boundary. VCC Levels During Manchester Communica- tion For all devices with UVLO functionality, after power-up, it is important that the VCC pin be held at VCC until the first Synchronization pulse of a read/write transaction is sent (see Figure 27). During the transaction, the VCC pin varies between VMAN(H) and VMAN(L), but after the last CRC bit has been sent, the controller must bring the VCC pin back to the VCC level in less than tMAN_VCC. This is important in order to avoid triggering the UVLO functionality during EEPROM read/write.
