Wait condition I2CEN = 0 To force the M3L-master to interrupt the transmission sequence until MEGATEXT is ready for more data, MEGATEXT can force down SCL after the transmission of a complete byte. At that time the bus master has to switch its SCL-output to high impedance and check the state of SCL afterwards.During SCL check I2CEN has to be low.

Reset/Chip Initialization A power-on reset or a reset pulse at pin RES lead to a hardware reset and a software initialization of registers and internal DRAM. During initialization bus transfers are not allowed. At / after power-on a reset pulse at pin RES is necessary. RES may return to 0 after the supply voltage reached its lower limit for chip function (4.7 V). This may be achieved by a capacitor C between RES and VDD and by a resistor R between RES and VSS. The dimensions of R and C depend on the worst case rise time of VDD. Initialization time after power- tINIT on or falling edge of RES Pulse width RES High level at pin RES causes chip reset. In rare cases, the IC may remain in a permanent reset state after power up, depending on the applicational context. After power up, the software should check proper operation. In case the Megatext does not react properly, power supply should be switched off for at least 3 s. After that, power supply can be switched on again.
