C host interface features are:
 I

C Multi-Master Mode - module initiates clock and data, operating speed 400kbps.
 I
2
C address ‘0x60’ for RX and ‘0x62’ for TX.
 Individual transmit and receive FIFO length of 64 bytes.
 I

C host interface mode can be switched slave (Multi-master default), clock rate can be
switched 100KHz (default 400KHz), address can be changed (default 0x62 for TX FIFO and
0x60 for RX FIFO) by sending OSP Message ID 178, Sub ID 2 input command.
 SCL and SDA are pseudo open-drain lines, therefore require external pull-up resistors of
2.2kΩ to 1.8V, or 3.3kΩ to 3.3V.
