8.9.5. Slave Address

2
The I C-Bus device does not include a chip select pin such as is found in ordinary logic devices. Instead of
using a chip select pin, slave addresses are allocated to each device.
All communications begin with transmitting the [START condition] + [slave address (+ R/W specification)]. The
receiving device responds to this communication only when the specified slave address it has received matches
its own slave address.
Slave addresses have a fixed length of 7 bits. This RTC's slave address is [0110 010*].
An R/W bit ("*" above) is added to each 7-bit slave address during 8-bit transfers.
