Internal Register Definition 1. I2CCLOCK: I2C Clock Frequency Configuration
The transaction time-out counter, which terminates an I2C transaction after a set period of time has passed, can be
configured through the I2CTO Internal Register. If the time-out counter is not enabled, the CP2120 will make only
one attempt at executing an I2C transaction and abort if that transaction attempt fails.
Equation 2. CTO Time-Out Frequency
Internal Register Definition 2. I2CTO: I2C Time Out
The SPI Master can assign an I2C address to the CP2120 by writing to the I2CADR Internal Register. Setting this
address is not necessary for device operation. If set, the CP2120 will ACK this address when another I2C Master
on the bus attempts to communicate with it. The CP2120 will NACK all attempts at data transfer when responding
as an I2C slave.
