template<typename TransportT >
Start-up sequence for SE050 erratum I2C.1, then resynchronise the block numbers.
Errata sheet Rev. 1.0, 3.1.3: if the host resets in the middle of an exchange, the SE050 may still hold an answer; writing the next command before it is read can make the SE050 stretch SCL until it is power-cycled. Call this once after the host starts, before the first command: it reads (and discards) any pending block, then sends S(RESYNCH request) and resets N(S)/N(R) on both sides. When nothing is pending the read is simply NACKed (it costs ReadRetries x ReadRetryDelayMs). It cannot clear a lock-up that has already happened: that needs a power cycle (HardwareReset()).
