CP2400/1/2/3
6.
The CP2400/1/2/3 is controlled by internal registers and provides the system with up to 256 bytes of additional
RAM. The internal registers and memory are controlled through an indirect interface accessible through a 4-wire
SPI interface (CP2400/2) or 2-wire SMBus/I
RAM is shown in Figure 6.1. The internal registers are listed in “6.3. Internal Registers” on page 37.
