ZL50404

Data Sheet

An ABORT command is detected when DATAIN is sampled low when STROBE- rise and DATAIN is sampled high

when STROBE- fall.

3.3.1

Write Command

All registers in ZL50404 can be modified through this synchronous serial interface. Once the data has been sent,

two extra STOBE clocks must be generated to indicate the end of the write command. The DATAIN line should be

held high for these two pulses.
