New content can be written into the configuration register (the contents of the output register cannot be changed). To write new content, address the ADS1000-Q1 for writing, and write one byte to the device. This byte is written into the configuration register.

Writing more than one byte to the ADS1000-Q1 has no effect. The ADS1000-Q1 ignores any bytes sent after the first one, and only acknowledges the first byte. Figure 7-4 shows a timing diagram of an ADS1000-Q1 write operation.
