Receiver/Transmitter
Data Transfer Rate
Provides both slave write and
Standard mode at 100kbits/s
This serial protocol is designed to allow both blocks write and read from the controller. The
bytes must be accessed in sequential order from lowest to highest byte. Each byte transferred
terminate the transfer. The write or read block both begins with the master sending a slave
address and a write condition (0xD2) or a read condition (0xD3).
Following the acknowledge of this address byte, in
Write Mode:
the
Command Byte
and
Byte
Count Byte
must be sent by the master
but ignored by the slave, in
Read Mode:
the
Byte
Count Byte
will be
read by the master
then all other
Data Byte
.
Byte Count Byte
default at
power-up is = (0x09).
