Description
I²C ratio is determined by the following:
f_SCL = 6.25 MHz / register value (in
decimal)
0x40'h = ~100 kHz SCL (default)
Note: Register values <0x32'h are NOT
supported.
Deserializer Device ID = 0x60
(1100_000X) default
Reserved
Slave Device ID. Must be programmed to
communicate with remote slave device
