( please refer to PAS6337 register description ) during write cycle, the master generate s start condition and then places the 1 st byte data that are combined slave address ( 7 bits ) with a read / write control bit to sda line. after slave ( PAS6337 ) issues acknowledgment, the master places 2 nd byte ( sub address ) data on sda line. again follow the PAS6337 acknowledgment, the master places the 8 bits data on sda line and transmit to PAS6337 control register ( address was assigned by 2 nd byte ). after PAS6337 issues acknowledgment, the master can generate a stop condition to end of this write cy cle. in the condition of multi-byte write, the PAS6337 sub-address is automatically incremen t after each data byte transferred. the data and a cycles is repeat until last byte write. every control registers value in side PAS6337 can be programming via this way. slave transmits data to master ( read cycle ) z the sub-address was taken from previous write cycle. z the sub-address is automatically increment after each byte read. z am : acknowledge by master. z note there is no acknowledgment fr om master after last byte read. during read cycle, the master genera tes start condition and then place the 1 st byte data that are combined slave address ( 7 bits ) with a read / write control bit to sda line. after issue acknowledgment, 8 bits data was also placed on sda line by PAS6337. the 8 bits data was read from PAS6337 internal control register that address was assigned by previous wr ite cycle. follow the master acknowledgment, the PAS6337 place the next 8 bits data ( address is incr ement automatically ) on sda line and then transmit to master serially. the data and am cycles is repeat until the last byte read. after last byte read, am is no longer generated by master but instead by keep sda line high. the slave ( PAS6337 ) must releases sda line to master to generate stop condition.
