5.1. Command Set
An SPI Master controls the CP2120 by sending commands across the SPI bus. Some commands initiate I2C
transactions, while other commands modify or monitor CP2120 operation and events.
5.2. Internal Registers
The CP2120 maintains a set of internal registers that can be modified to configure general purpose port I/O and I2C
operation and can be read to obtain device status. Commands reading to and writing from the internal registers can
be issued at any time, even while an I2C transaction is in progress, as they do not initiate any I2C bus transactions.
Table 3 shows a list of all internal registers.
5.2.1. Write to Internal Register
A Write to Internal Register command updates the value of one of the CP2120's Internal Registers. A Write to
Internal Register command begins with the command byte, 0x20, followed by the internal register address,
followed by the new value of the internal register. Only one register can be accessed per Write to Internal Register
command.
