(2) Data Write in S-35392A
After detecting a start condition, S-35392A receives device code and command. The S-35392A enters the
Write-data mode by the Read/Write bit “0”. Input data from B7 to B0 in 1-byte. The S-35392A outputs an
acknowledgment signal (“L”) every moment that 1-byte data is input. After receiving the acknowledgment signal
which is for the last byte-data, input a stop condition to the S-35392A to finish access.
